Adding a new bathtub may improve the look and functionality of your bathroom. However installing a bathtub is not always easy, and homeowners may make some typical blunders if they are not aware of the proper methods or processes. Making sure you avoid these typical mistakes will allow your new tub to be fitted correctly the first time, saving you money, and time.
In this article, we will give a brief description of the five most common mistakes made during bathtub installation. Being aware of them in advance makes it easier to install the bathtub properly while maintaining the beauty and functionality of the sanitaryware for many years to come.
Common Errors in Bathtub Installation and How to Prevent Them
When installing or replacing a bathtub, a lot of things may go wrong if you don’t manage things correctly. The following are the top five mistakes individuals make while building bathtubs.
1. Incorrect Measurements
A common mistake when installing a new bathtub is inaccurate measurements. It’s essential to measure both the space for the existing tub and the new one carefully. A poor fit might result from even a little mistake. Leave extra room for fixtures like faucets and showerheads.
A clearance of ¼ to ½ inch around the tub is recommended for proper fitting and caulking. Additionally, check the plumbing rough-in measurements to ensure the drain aligns with your new tub’s connections. Always follow the manufacturer’s specifications to avoid installation issues and prevent damage to the floor or tub.
2. Improper Plumbing Connections
A key part of bathtub installation is properly connecting the drain and water supply lines. If not done correctly, leaks, blockages, and other issues can arise. Always follow the manufacturer’s instructions for drain assemblies, overflows, and water supplies. Modern tubs typically have pre-drilled drain holes, making alignment easier, especially for freestanding tubs.
Ensure the shoe and collar are aligned and tightly secured. Use plumber’s putty around drains and overflows to prevent leaks. When connecting hot and cold water supplies, use the correct bath valve and shut-off valves, and seal joints with pipe dope or tape to avoid leaks and water damage.
3. Ignoring Floor Support Requirements
Modern bathtubs are much heavier than traditional clawfoot models, especially when filled with water and a bather. Failing to properly support the tub can lead to cracked tiles or even floors sinking. Check your tub’s documentation for its fill weight. For most standard tubs, a ¾” plywood subfloor, securely screwed into joists or foundations, is ideal.
You may need to add extra joists or blocking to reinforce the floor before installing the plywood. Strengthening the floor where your tub will sit ensures it stays level and supported, preventing damage and providing long-term stability. This step is essential and should not be skipped.
4. Poor Sealing And Waterproofing
Sealing your bathtub properly during installation is crucial to prevent water from damaging your flooring and subfloor. Water wastage and the formation of mould can result from leaks. Apply a generous bead of silicone caulk around the tub’s rim where it meets surrounding surfaces.
Smooth it with a wet finger for an even, continuous seal. Silicone caulk is ideal because it’s waterproof and won’t absorb water. For added protection, consider applying waterproof paint to exposed bathroom walls to prevent leaks from reaching the floor, helping you avoid costly repairs in the future.
5. Skipping The Levelling Process
A bathtub that isn’t level can cause water to pool unevenly, leading to uncomfortable bathing and safety issues, like the tub sloping to one side. Luckily, leveling your tub is an easy fix with a little time and effort. To check, place a spirit level lengthwise and crosswise along the tub’s rim. For minor adjustments, use plastic shims under the tub if it’s made of plastic.
For larger discrepancies, you may need to detach and reposition the tub. Ensure the tub sits flush with the floor, and shim it securely to fix any wobbling before completing tile or wall work. Proper leveling ensures both functionality and visual appeal.
