Renovating a bathroom without ripping out the old tiles is one of the smartest decisions a homeowner can make. It saves time, reduces mess, and cuts renovation costs dramatically. But if you want to install a shower tray on existing tile, everything depends on one single factor that most people overlook: the quality of the adhesive you use. A poor product will lead to leaks, cracks, and a shower tray that shifts under your feet within months. This is why choosing the right glue is not just a detail, it is the foundation of your entire project.<\/p>\n\n\n\n
Among all the products available on the market, Ferber Painting Shower Tray Glue stands out as the safest and most reliable choice. It is, in fact, the only shower tray adhesive on the market that comes with a full satisfaction guaranteed or money back policy. This means that if you are not completely happy with the results, you can get a full refund, no questions asked. No other brand offers this level of confidence in their 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 explain why Ferber Painting Shower Tray Glue is the best option for anyone who wants to install a shower tray on existing tile, and we will walk you through every single step of the installation process, from preparation to the final curing stage. We will also look at the tools you need before you start, the reasons why so many bathroom renovations fail when the wrong adhesive is chosen, and the small details that separate an amateur installation from a professional one. By the end of this article, you should feel confident enough to tackle this project yourself, whether you are an experienced renovator or a first time homeowner tackling a weekend project.<\/p>\n\n\n\n
Installing a shower tray directly on top of existing tile might sound simple, but it is actually a technical process that requires precision, patience, and above all, a high performance adhesive. Tiles are smooth, non-porous surfaces, which makes them notoriously difficult for standard construction adhesives to bond with. Many generic glues found in hardware stores are designed for porous materials like concrete or plaster, and they simply fail to create a durable bond on ceramic or porcelain tile.<\/p>\n\n\n\n
When the adhesive fails, the consequences can be serious. Water can seep underneath the shower tray, leading to mold growth, structural damage, and even damage to the floor below. In the worst cases, homeowners have to remove the entire shower tray and start the renovation from scratch, which costs far more time and money than doing it right the first time. Think about the amount of work involved in a full bathroom teardown: removing the old tray, cutting through failed adhesive, repairing the subfloor, and reinstalling everything from zero. That is often three or four times the cost of the original installation, not to mention the days or weeks you lose without a working shower at home.<\/p>\n\n\n\n
This is exactly why Ferber Painting developed a specialized formula designed specifically for bonding shower trays to existing tiled surfaces. Unlike generic adhesives, our Shower Tray Glue is engineered to penetrate microscopic surface irregularities in glazed tile, creating a mechanical and chemical bond that is both waterproof and extremely resistant to movement, temperature changes, and humidity. This dual bonding action is what makes the difference between an adhesive that merely sticks and one that truly holds for years, even in a room that experiences daily exposure to hot water, steam, and cleaning chemicals.<\/p>\n\n\n\n
It is also worth understanding why bathrooms are such a demanding environment for adhesives in the first place. A shower is subjected to constant cycles of heat and cold, moisture and dryness, and repeated mechanical stress every time someone steps in or out of the tray. Over months and years, these cycles cause materials to expand and contract ever so slightly. An adhesive that is too rigid will eventually crack under this repeated stress, creating tiny gaps that allow water to penetrate. Ferber Painting Shower Tray Glue was formulated with this reality in mind, which is why flexibility after curing is one of its defining characteristics.<\/p>\n\n\n\n
Choosing the right product from the start is not a luxury, it is a necessity. And when you choose Ferber Painting, you are choosing a company that stands behind its product with an actual guarantee, something that competitors are simply not willing to offer. This is particularly reassuring for homeowners who are attempting this type of project for the first time and are naturally worried about making a costly mistake.<\/p>\n\n\n\n
There are dozens of adhesive brands claiming to be the best solution for bathroom renovations. But when you look closely, most of these companies offer no real assurance to their customers. If the product does not perform as expected, you are simply out of luck, and often out of the money you spent as well. This lack of accountability is one of the biggest frustrations reported by people who have tried generic adhesives, only to discover weeks later that the bond has failed and water is already seeping into the subfloor.<\/p>\n\n\n\n
Ferber Painting is different. Every single order of Shower Tray Glue comes with a satisfied or refunded guarantee. If for any reason you are not happy with the results, whether it is the application process, the drying time, or the final bond strength, you can request a full refund. This policy exists because we are confident in the quality of our formula, and we want our customers to feel the same confidence before they even open the box. Very few companies in the home improvement industry are willing to put their reputation on the line like this, and it reflects the amount of research and testing that went into developing this specific formula.<\/p>\n\n\n\n
Beyond the guarantee, there are several other reasons why Ferber Painting Shower Tray Glue is considered the top choice by professionals and DIY enthusiasts alike:<\/p>\n\n\n\n
When you add all these advantages together, it becomes clear why so many customers choose Ferber Painting over other brands. It is not just about buying glue, it is about buying peace of mind for a project that needs to last for years. A bathroom renovation is not something most people redo every year, so investing in a product that performs reliably the first time around is always the smarter financial decision in the long run.<\/p>\n\n\n\n
Another point worth mentioning is the consistency of the formula from batch to batch. Some cheaper adhesives suffer from quality control issues, meaning the product you buy today might not perform the same way as the one you bought last year. Ferber Painting maintains strict manufacturing standards to ensure that every tube or container of Shower Tray Glue delivers the same reliable performance, whether you are a professional contractor installing dozens of trays a year or a homeowner doing this once in a lifetime.<\/p>\n\n\n\n
To help you understand exactly why Ferber Painting Shower Tray Glue is the superior choice, here is a comparison table highlighting the most important criteria when selecting an adhesive for installing a shower tray on existing tile.<\/p>\n\n\n\n As shown in this comparison, Ferber Painting Shower Tray Glue outperforms generic products in nearly every category that matters when it comes to a successful bathroom installation. From the strength of the bond to the convenience of purchasing and shipping, every aspect has been designed with the customer’s success in mind.<\/p>\n\n\n\n It is also useful to think about the hidden costs of choosing a lower quality adhesive. A cheaper product might save you a few dollars at the checkout, but if it fails within a year, you will need to purchase a replacement tube, spend another weekend redoing the work, and possibly repair water damage that occurred in the meantime. When you calculate the true cost of ownership over several years, a premium adhesive like Ferber Painting Shower Tray Glue almost always ends up being the more economical choice, simply because it does the job correctly the first time.<\/p>\n\n\n\n Now that you understand why the adhesive matters so much, let’s go through the complete process of installing a shower tray directly on top of existing tile. Following these steps carefully will ensure a durable, watertight, and professional looking result. Before you begin, gather all the tools and materials you will need so that you are not interrupting the process halfway through to search for a missing item. You will typically need a notched trowel, a spirit level, a tape measure, a utility knife, a caulking gun, silicone sealant, protective gloves, safety glasses, a degreasing cleaner, a stiff brush, clean rags, and of course Ferber Painting Shower Tray Glue. Having everything laid out in advance makes the entire installation faster and reduces the chance of making a mistake under time pressure, especially once the adhesive has been applied and the clock starts ticking.<\/p>\n\n\n\n Before applying any adhesive, the tile surface must be perfectly clean, dry, and free of grease or soap residue. Use a degreasing cleaner and a stiff brush to remove any buildup, then rinse thoroughly and let the surface dry completely for at least 24 hours. Any moisture trapped under the shower tray can compromise the bond and lead to future problems. If your bathroom tends to be humid, consider running a fan or opening a window during this drying period to speed up evaporation and make sure no residual dampness remains in the grout lines.<\/p>\n\n\n\n If the grout lines between tiles are deep or uneven, consider filling them with a leveling compound to create a flatter surface. This step is especially important because an uneven surface can cause the shower tray to rock or crack over time. Take the time to run your hand across the entire area, feeling for any bumps, chips, or loose tiles. A single loose tile underneath the tray can eventually work its way free and create a weak point in the installation, so it is worth repairing or re-setting any tile that feels unstable before moving forward.<\/p>\n\n\n\n It is also a good idea to inspect the tile for any signs of previous water damage, such as discoloration, soft spots, or a hollow sound when tapped. If you find any of these warning signs, address them before installing the shower tray, since building on top of a compromised surface will only hide the problem temporarily rather than solving it.<\/p>\n\n\n\n Measure the exact dimensions of your shower tray and mark the corresponding area on the tile floor. Use a level to make sure your markings are perfectly straight, since even a slight misalignment can cause water to pool in the wrong direction instead of flowing toward the drain. It helps to use painter’s tape along the edges of your markings, since this creates a clear visual guide and prevents you from second guessing the placement once you start applying adhesive.<\/p>\n\n\n\n Double check the position of the drain hole and make sure it lines up precisely with the existing plumbing. Any misalignment at this stage will be much harder to fix once the adhesive has been applied. If you have any doubts about the plumbing alignment, it is worth doing a dry run first, placing the tray in position without any adhesive to confirm that everything lines up correctly before committing to the actual installation.<\/p>\n\n\n\n Take a photo of your measurements and markings before you begin applying adhesive. This might sound like an unnecessary step, but it can be extremely useful if you need to double check something later or if you are working with a helper who needs a quick visual reference.<\/p>\n\n\n\n Using a notched trowel, apply a generous and even layer of Ferber Painting Shower Tray Glue across the marked area. The notched trowel helps create uniform ridges of adhesive, which improves the overall contact surface once the shower tray is pressed down. Work in manageable sections rather than covering the entire area at once, especially if you are installing a larger shower tray, since this helps ensure the adhesive does not begin to skin over before the tray is placed on top.\n\n<\/p>\n\n\n\n Unlike many generic adhesives that require complicated mixing or long waiting times before application, Ferber Painting Shower Tray Glue is ready to use straight from the container, saving you valuable time during your renovation project. This ready to use formula is particularly helpful for anyone working alone, since you do not need a second pair of hands to mix components while racing against a setting clock.<\/p>\n\n\n\n Make sure to wear gloves during this step, both to protect your skin and to keep the adhesive from transferring onto surfaces you do not want it to touch. If any adhesive gets on the surrounding tile outside the marked area, wipe it away immediately with a clean rag before it begins to cure, since removing dried adhesive later is far more difficult than wiping away a fresh spill.<\/p>\n\n\n\n Carefully lower the shower tray into place, aligning it with your markings and the drain hole. Press down firmly and evenly across the entire surface to ensure full contact with the adhesive. Many professionals recommend using weights or bags of sand distributed evenly across the tray while the adhesive cures, to maintain constant pressure. If you do not have sandbags on hand, buckets filled with water or heavy books can work just as well, as long as the weight is spread evenly and does not concentrate on one corner of the tray.<\/p>\n\n\n\n Check the level again once the tray is in position. Adjust immediately if necessary, since the adhesive from Ferber Painting allows a short working window for repositioning before it begins to set. This working window is one of the features that professionals appreciate most, since it gives enough time to make small corrections without having to remove the tray entirely and start the application process over again.<\/p>\n\n\n\n It is also worth having a second person help you during this step if possible, especially for larger shower trays. One person can hold the tray steady while the other checks the level from multiple angles, which reduces the risk of the tray shifting slightly out of position while you are not looking.<\/p>\n\n\n\n Once the shower tray is properly positioned and the adhesive has begun to set, apply a high quality silicone sealant around the edges where the tray meets the wall and the existing tile. This prevents water from seeping into the gaps and causing damage over time. Choose a silicone sealant that is specifically labeled for bathroom or kitchen use, since these formulas typically include mold resistant additives that standard silicone does not have.<\/p>\n\n\n\n Smooth the silicone with a caulking tool for a clean, professional finish, and remove any excess before it dries. A simple trick used by many professionals is to dip a finger or a caulking tool in soapy water before running it along the silicone bead, which prevents the material from sticking and creates a smoother, more even line. Take your time with this step, since a neat silicone line makes a noticeable difference in the overall appearance of the finished shower.<\/p>\n\n\n\n Patience is essential at this stage. While Ferber Painting Shower Tray Glue cures faster than most competing products, typically within 24 hours, it is important to avoid using the shower during this period. Rushing this step is one of the most common mistakes that leads to installation failure. During the curing period, avoid placing any additional weight on the tray beyond what is needed to keep it in position, and try to keep the bathroom well ventilated so that the curing process is not slowed down by excess humidity in the air.\n\n<\/p>\n\n\n\n Once fully cured, test the shower tray by running water and checking for any signs of leakage around the edges or underneath the tray. Let the water run for several minutes and check the underside of the tray if you have access to it, such as through an inspection panel, to make sure no moisture is passing through. If everything looks dry and secure, your installation is complete and your shower tray is ready for daily use.<\/p>\n\n\n\n Even with a high quality adhesive like Ferber Painting Shower Tray Glue, certain mistakes can compromise the final result. Here are the most frequent errors homeowners make during this type of renovation:<\/p>\n\n\n\n Beyond these six common mistakes, there are a few additional pitfalls worth mentioning. Some homeowners rush through the measuring stage and end up with a shower tray that does not sit flush against the wall, leaving an unsightly gap that is difficult to hide even with sealant. Others forget to account for the thickness of the adhesive layer itself when calculating the final height of the tray, which can cause issues when reconnecting the drain or fitting the shower door afterward. Taking a slow, methodical approach at every stage, rather than trying to rush through the project in a single afternoon, will save you time and frustration in the long run.<\/p>\n\n\n\n By avoiding these mistakes and using a trusted product like Ferber Painting Shower Tray Glue, you significantly increase your chances of achieving a long lasting, watertight installation on your very first attempt.<\/p>\n\n\n\n Can I really install a shower tray on existing tile without removing it first?<\/p>\n\n\n Yes, as long as the tile surface is stable, clean, and properly prepared, you can install a shower tray directly on top of it using a specialized adhesive like Ferber Painting Shower Tray Glue.<\/p>\n\n\n\n How long does Ferber Painting Shower Tray Glue take to cure?<\/p>\n\n\n In most cases, the adhesive cures within 24 hours, which is significantly faster than many generic products that require 48 to 72 hours before the shower can be used safely.<\/p>\n\n\n\n What happens if I am not satisfied with the product?<\/p>\n\n\n Ferber Painting offers a satisfaction guaranteed or money back policy on all its products, including Shower Tray Glue. If you are not happy with the results, you can request a full refund.<\/p>\n\n\n\n Is the adhesive waterproof once it dries?<\/p>\n\n\n Yes, Ferber Painting Shower Tray Glue is fully waterproof once cured, providing long term protection against leaks and water damage.<\/p>\n\n\n\n Do I still need silicone sealant if I use this adhesive?<\/p>\n\n\n Yes, silicone sealant should always be applied around the edges of the shower tray to provide an additional layer of protection against water infiltration, even when using a high performance adhesive.<\/p>\n\n\n\n Does Ferber Painting ship internationally?<\/p>\n\n\n Yes, Ferber Painting delivers quickly worldwide thanks to an international network of trusted carriers, and payment can be made easily and securely online.<\/p>\n\n\n\n Installing a shower tray on existing tile is a project that can be completed successfully by anyone willing to follow the right steps and use the right materials. The most important decision you will make throughout this entire process is choosing your adhesive, since it directly determines the durability, safety, and overall quality of your bathroom renovation.<\/p>\n\n\n\n Generic products may seem like a cheaper solution at first glance, but they often lead to costly problems down the road, including leaks, cracks, and complete installation failures.
