Installing a recessed shower tray is one of those bathroom renovation projects that looks simple on paper but can quickly turn into a nightmare if you use the wrong materials. Before we even talk about tools, measurements, or waterproofing techniques, there is one truth that every experienced installer will tell you: everything depends on the quality of the adhesive you choose. A poorly bonded shower tray will move, crack the surrounding tiles, and eventually leak, causing water damage that can cost thousands to repair. This is why choosing the right product from the very beginning is the single most important decision you will make in this entire project.<\/p>\n\n\n\n
That is exactly why we recommend Ferber Painting Shower Tray Glue. Unlike most adhesives on the market, our formula is specifically engineered for the unique stresses that a shower tray experiences: constant humidity, temperature fluctuations, and the weight of people standing on it every day. But what truly sets us apart is something no other brand on the market offers: a satisfied or refunded guarantee. If you are not completely happy with the result, we refund you, no questions asked. No competitor in this niche offers that level of confidence in their own product, and that alone should tell you something about the quality you are getting.<\/p>\n\n\n\n
In this complete guide, we will walk you through everything you need to know about installing a recessed shower tray, from selecting the right materials to the final waterproofing checks. We will also explain, step by step, why Ferber Painting Shower Tray Glue is simply the best choice for this type of job, and how it compares to other products you might find in hardware stores or on generic online marketplaces. Whether you are a seasoned tiler renovating a client’s bathroom or a homeowner tackling your very first plumbing project, this guide is written to give you the confidence and knowledge you need to get the job done right the first time, without costly rework or unpleasant surprises months down the line.<\/p>\n\n\n\n
Many DIY enthusiasts underestimate the importance of the adhesive used to secure a shower tray. They assume that any generic construction glue or mortar will do the job. This is a costly mistake. A shower tray is subjected to constant water exposure, weight pressure, and thermal expansion and contraction. If the adhesive is not flexible enough, not waterproof enough, or does not cure properly, the tray will eventually shift, crack the tile joints, and create gaps where water can seep through.<\/p>\n\n\n\n
Think about what actually happens to a shower tray on a daily basis. Every time someone steps in, the tray flexes ever so slightly under the weight. Every time hot water runs, the material expands a fraction of a millimeter, and when the water is turned off and the room cools down again, it contracts back. Multiply that cycle by thousands of showers over the years, and you start to understand why a rigid, brittle adhesive that cannot absorb any of that movement is almost guaranteed to fail eventually. The failure is rarely dramatic. It usually starts as a hairline crack in the grout near the edge of the tray, barely visible, easy to ignore. Months later, that hairline crack becomes a path for water to travel underneath the tray, where it sits against the subfloor, unseen, slowly causing rot, mold, and structural damage that can be extremely expensive to repair.<\/p>\n\n\n\n
Ferber Painting Shower Tray Glue was developed specifically to solve these problems. It is a hybrid polymer adhesive that combines the strength of traditional construction adhesives with the flexibility needed to absorb the natural micro-movements of a bathroom floor. Here are the main reasons why professionals and DIYers alike choose our product over the competition.<\/p>\n\n\n\n
Most competing adhesives on the market focus only on one or two of these criteria. Some are strong but not flexible, which leads to cracking. Others are waterproof but take days to cure, delaying your entire renovation project. Ferber Painting Shower Tray Glue was designed to check every box at once, which is why it has become the preferred choice for bathroom professionals across Europe and beyond.<\/p>\n\n\n\n
Another aspect that is often overlooked is how the adhesive behaves in tricky, real-world conditions rather than in a laboratory setting. Bathrooms are rarely perfectly flat, walls are rarely perfectly square, and recesses often have small irregularities left over from previous installations. A high performing adhesive needs to be forgiving enough to fill minor gaps while still curing to a strong, stable bond. Our formula has been tested by professional installers in exactly these imperfect, real-life conditions, not just in ideal laboratory environments, which is why it consistently performs well even on older or slightly uneven substrates.<\/p>\n\n\n\n
To help you understand why Ferber Painting Shower Tray Glue stands out, we have put together a comparison table that highlights the most important criteria when choosing an adhesive for this type of job. We compared our product with two typical alternatives you would find in a standard hardware store: a generic silicone based adhesive and a traditional cement mortar mix.<\/p>\n\n\n\n As you can see, Ferber Painting Shower Tray Glue offers a level of convenience, performance, and peace of mind that generic alternatives simply cannot match. When you also consider that our product is available directly on our website with fast international shipping and secure online payment, the choice becomes even clearer.<\/p>\n\n\n\n It is worth digging a little deeper into each of these criteria, because they are not just marketing talking points, they translate directly into real consequences for your renovation project. Take curing time, for example. If you use a traditional cement mortar mix that needs 48 to 72 hours to cure fully, you effectively lose three days of work on your bathroom. For a professional tradesperson, that means three days without being able to invoice a client for progress, and three days during which the job site needs to remain undisturbed. For a homeowner, that means three extra days without access to a functioning shower, which is a real inconvenience for a family. With Ferber Painting Shower Tray Glue, that waiting period is reduced to a fraction of the time, letting you keep your renovation schedule on track.<\/p>\n\n\n\n Flexibility is another criterion that is easy to underestimate until you have seen the consequences of using a rigid adhesive firsthand. We have heard from countless customers who previously used a traditional mortar bed to install their shower tray, only to notice cracks appearing in the grout lines within a year or two. Once we explain that a rigid adhesive cannot absorb the natural flex of the floor and the tray, the problem suddenly makes sense to them. This is precisely the kind of long-term issue that our hybrid polymer formula was designed to prevent from the very beginning.<\/p>\n\n\n\n Before starting the installation, it is important to gather all the necessary tools and materials. Having everything ready before you begin will save you time and prevent unnecessary interruptions during the process, especially since some adhesives, including ours, require a certain working time before they start to cure.<\/p>\n\n\n\n Having all of these items on hand before you begin will make the entire process smoother and significantly reduce the risk of mistakes during installation. It is also a good idea to prepare a few additional items that, while not strictly mandatory, can make the job considerably easier. A cordless drill with a mixing attachment can be useful if you are also preparing a leveling compound for the floor. A wet cloth or sponge kept nearby will help you clean up any excess adhesive that squeezes out from under the tray before it starts to cure, since cleaning it up while it is still fresh is far easier than trying to scrape off cured adhesive later. A small torch or work light can also be helpful if you are installing the tray in a recess with limited natural light, allowing you to check the edges and corners more carefully.<\/p>\n\n\n\n If you are working with an acrylic or resin tray, consider also having some cardboard or a protective covering on hand to place inside the tray once it is positioned. This prevents accidental scratches or damage from tools or debris while you continue working on the surrounding walls and plumbing connections. Many installers skip this simple precaution and end up with visible scratches on a brand new tray, which is a frustrating and entirely avoidable mistake.<\/p>\n\n\n\n Now that we have covered why the adhesive matters and what tools you need, let us go through the actual installation process in detail. Follow these steps carefully to ensure a professional result that will last for years.<\/p>\n\n\n\n Start by making sure the recess where the shower tray will sit is clean, dry, and free of debris. Remove any old flooring, adhesive residue, or dust. The surface needs to be as flat and even as possible, because any irregularities can create gaps under the tray, which will weaken the bond and increase the risk of future leaks. If necessary, use a leveling compound to smooth out the floor before proceeding.<\/p>\n\n\n\n Take the time to inspect the subfloor itself, not just its surface. If you are working on a wooden subfloor, check for any signs of rot, soft spots, or previous water damage that might need to be repaired before you continue. Installing a beautiful new shower tray on top of a compromised subfloor is a recipe for problems down the line, no matter how good the adhesive is. If you find any damaged sections, replace them with new, properly treated plywood or boards rated for wet areas before moving forward. For concrete subfloors, check for cracks or uneven patches, and address them with an appropriate filler or leveling compound. Allow any leveling compound to cure fully according to its instructions before applying the adhesive, since applying the tray too soon on a compound that has not fully hardened can compromise the entire installation.<\/p>\n\n\n\n Before placing the tray, verify that the drainage pipe is correctly positioned and at the right height to connect with the tray’s waste outlet. This step is crucial because once the tray is glued in place, adjusting the plumbing becomes far more complicated. Take the time to do a dry fit of the tray, without adhesive, to confirm that everything aligns properly.<\/p>\n\n\n\n During this dry fit, it is also worth checking the slope of the drainage pipe itself. A shower drain needs a slight downward slope to allow water to flow away efficiently rather than pooling near the outlet. If your pipe was installed with insufficient slope, now is the time to correct it, before any adhesive is applied. It is also a good idea to test the drain with a bucket of water at this stage, watching how quickly and completely it empties, so that any issues can be identified and fixed while access is still easy.<\/p>\n\n\n\n Using your tape measure and pencil, mark the exact position where the tray will sit. Double check the measurements against the tray’s dimensions and the recess to avoid any surprises later. Precision at this stage will save you a lot of frustration during the actual installation.<\/p>\n\n\n\n It can be helpful to mark not just the outer edges of the tray but also a few reference points along the middle of the recess, especially for larger trays. These reference marks act as a visual guide when you are lowering the tray into place, helping you center it correctly on your first attempt rather than needing to lift and reposition it, which can disturb the freshly applied adhesive.<\/p>\n\n\n\n This is where the quality of your adhesive truly makes a difference. Using the notched trowel, apply Ferber Painting Shower Tray Glue evenly across the base of the recess, making sure to cover the entire surface that will be in contact with the tray. Our formula is designed to be easy to spread, even for beginners, thanks to its smooth consistency that does not slump or run before the tray is placed.<\/p>\n\n\n\n Unlike traditional cement based mortars, which require precise mixing ratios and can dry unevenly, our adhesive comes ready to use, eliminating a common source of error for DIY installers. This alone significantly reduces the risk of an uneven or weak bond.<\/p>\n\n\n\n When applying the adhesive, work in a methodical pattern, starting from one corner of the recess and moving steadily across the entire surface, rather than applying it randomly in patches. A consistent notched pattern, similar to what you would use when tiling, ensures uniform coverage and allows any trapped air to escape as the tray is pressed down, rather than becoming trapped in pockets that could later collapse under weight. Pay particular attention to the corners and edges of the recess, since these areas often receive less coverage than the center if you are not careful, yet they are just as important for a stable, watertight bond.<\/p>\n\n\n\n Carefully lower the shower tray into place, aligning it with the marks you made earlier. Press down firmly and evenly across the entire surface to ensure full contact with the adhesive. If needed, use the rubber mallet gently to tap the edges into place, but be careful not to apply excessive force that could damage the tray or displace the adhesive unevenly.<\/p>\n\n\n\n Ideally, this step should involve two people, especially for larger trays, so that the tray can be lowered evenly on all sides at the same time. If you are working alone, lower one edge first, guiding it into its final position, and then gradually lower the rest of the tray while checking that it remains aligned with your reference marks. Avoid sliding the tray once it has made contact with the adhesive, since this can smear the adhesive unevenly and create weak spots. Instead, lift and reposition it if needed, then reapply a small amount of adhesive if the coverage has been disturbed.<\/p>\n\n\n\n Once the tray is in position, use the spirit level to check that it is perfectly horizontal in both directions. A tray that is not level will cause water to pool in certain areas instead of draining properly, which can lead to mold growth and unpleasant odors over time. Thanks to the strong initial grab of Ferber Painting Shower Tray Glue, once you confirm the tray is level, it will stay exactly where you place it without shifting.<\/p>\n\n\n\n Check the level not only along the two main axes of the tray but also diagonally across the corners, since a tray can appear level along its length and width while still being twisted slightly at one corner. If you notice a slight imbalance, gently apply pressure to the higher corner while the adhesive is still workable, and recheck the level immediately afterward. This small extra step at this stage can prevent a much bigger headache later when you notice water pooling in one corner of the finished shower.<\/p>\n\n\n\n This is one of the areas where our product truly shines. While many adhesives require 24 to 72 hours to cure fully, Ferber Painting Shower Tray Glue reaches a strong initial bond within just a few hours, allowing you to move forward with the rest of your bathroom renovation much faster. Of course, we still recommend avoiding heavy pressure or water contact during the first 24 hours to allow the adhesive to reach its full strength.<\/p>\n\n\n\n During this curing period, it is a good practice to place a temporary sign or barrier near the shower area to remind other household members not to step into the tray or place any weight on it. Even though the initial grab is strong, giving the adhesive its full recommended curing window before subjecting it to regular use will ensure the best possible long-term performance and durability of the bond.<\/p>\n\n\n\n Once the tray is securely bonded, apply a bead of silicone sealant around the edges where the tray meets the wall or the floor. This creates an additional barrier against water infiltration and gives the installation a clean, finished look. Smooth the sealant with a wet finger or a sealant tool for a professional finish.<\/p>\n\n\n\n Choose a silicone sealant that is specifically labeled for bathroom or sanitary use, as these formulas typically include mold inhibitors that help keep the joint looking clean over time. Apply painter’s tape along both sides of the joint before applying the sealant if you want an extra crisp, straight line, and remove the tape immediately after smoothing the bead, while the sealant is still workable, for the cleanest possible result.<\/p>\n\n\n\n With the tray securely in place, you can now connect the waste outlet to the drainage system. Make sure all connections are tight and test for leaks by running water through the drain before moving on to tiling or finishing the surrounding walls.<\/p>\n\n\n\n Run this water test for several minutes rather than just a few seconds, and check underneath the tray if access allows, or check the ceiling below if you are working on an upper floor, to make sure there are no slow, hidden leaks. It is far easier to correct a plumbing connection issue at this stage than after the surrounding walls have been tiled and finished.<\/p>\n\n\n\n Before considering the job complete, do a final inspection of the entire installation. Check that the tray is stable, that there is no movement when pressure is applied, that the seals are intact, and that water drains properly without pooling. This is also the moment to appreciate the difference a high quality adhesive makes: a tray installed with Ferber Painting Shower Tray Glue will feel completely solid, with no flex or movement whatsoever.<\/p>\n\n\n\n As part of this final inspection, take a few photographs of the completed installation, including the plumbing connections and the sealed edges. These photographs can be useful for your own records, especially if you ever need to refer back to how the installation was done, and they can also be helpful if you ever need to contact our customer service team with a question about your specific setup.<\/p>\n\n\n\n Even with the best adhesive on the market, certain mistakes can compromise the quality of your installation. Here are the most common errors we see, and how to avoid them.<\/p>\n\n\n\n Beyond these common errors, there are a few additional mistakes worth mentioning, since we see them repeated often enough to deserve special attention. One is failing to account for the weight and support requirements of certain tray materials. Stone resin trays, for example, are considerably heavier than acrylic ones, and while our adhesive is strong enough to support them, it is still important to ensure the subfloor itself is capable of bearing that additional weight over the long term, particularly on upper floors of older buildings.<\/p>\n\n\n\n Another frequent mistake is neglecting to protect the tray surface during the rest of the renovation. Installers sometimes glue the tray in place and then continue tiling the surrounding walls without any protective covering, leading to scratches, dropped tools, or accidental adhesive splashes on the tray surface. A simple sheet of cardboard taped loosely in place can prevent this kind of avoidable cosmetic damage to an otherwise perfect installation.<\/p>\n\n\n\n Finally, some installers forget to double check local building codes or manufacturer guidelines regarding waterproofing membranes in certain types of construction, particularly in multi-story buildings where water damage can affect the unit below. While Ferber Painting Shower Tray Glue provides excellent waterproofing at the bond line itself, it is always worth confirming that your overall waterproofing strategy, including any membrane behind the wall tiles, meets the requirements for your specific building and location.<\/p>\n\n\n\n By avoiding these common pitfalls and using a reliable product like Ferber Painting Shower Tray Glue, you can ensure a professional, long lasting installation that will serve you well for many years.<\/p>\n\n\n\n Once your recessed shower tray is installed and fully cured, a little bit of ongoing maintenance will help you get the most out of your investment. Regularly cleaning the tray surface with a mild, non-abrasive cleaner will prevent the buildup of soap scum and limescale, which can otherwise make the surface slippery and harder to clean over time. Avoid using harsh abrasive scouring pads on acrylic or resin trays, since these can scratch the surface and dull its finish.<\/p>\n\n\n\n It is also worth periodically inspecting the silicone seal around the edges of the tray, since this is typically the first part of the installation to show signs of wear. If you notice any discoloration, cracking, or peeling of the silicone, it is a good idea to remove the old sealant and reapply a fresh bead before any water has a chance to penetrate underneath. This small maintenance task, performed once every year or two depending on usage, will help protect the integrity of the underlying adhesive bond for the long term.<\/p>\n\n\n\n If you ever notice any unusual flexing, sound, or movement when stepping into the shower, this could be an early sign of a bonding issue and should be addressed promptly rather than ignored. With Ferber Painting Shower Tray Glue, such issues are extremely rare thanks to the strength and flexibility of our formula, but it is always good practice to stay attentive to how your shower tray feels underfoot over time.<\/p>\n\n\n\n How long does Ferber Painting Shower Tray Glue take to cure?<\/strong><\/p>\n\n\n The adhesive reaches a strong initial bond within a few hours, though we recommend waiting 24 hours before exposing the tray to water or heavy weight to allow it to reach full strength.<\/p>\n\n\n\n Can this adhesive be used on all types of shower trays?<\/strong><\/p>\n\n\n Yes, our formula is compatible with acrylic, resin, stone resin, and ceramic shower trays, making it a versatile choice regardless of the material you are working with.<\/p>\n\n\n\n What happens if I am not satisfied with the product?<\/strong><\/p>\n\n\n Ferber Painting offers a satisfied or refunded guarantee on all of its products, including the Shower Tray Glue. If you are not happy with the result, simply contact our customer service team for a full refund, no questions asked.<\/p>\n\n\n\n\n
