Remodeling a bathtub is more involved than most homeowners realize, and making the wrong choices early in the process can lead to expensive fixes later. Whether you are replacing a tub, refinishing one, or doing a full bathtub remodel, here are the most common mistakes to watch out for.
Choosing the wrong size tub is a surprisingly common error. A bathtub that is too large for the space makes the rest of the bathroom feel cramped, while one that is too small looks awkward and may not provide the bathing experience you want. Always measure the available space carefully and consider how the tub relates to the shower, vanity, and door swing. Our design team takes precise measurements during the consultation to ensure a perfect fit.
Ignoring the weight of the tub is another mistake that can have structural consequences. A large soaking tub or cast iron tub filled with water and a person can weigh over 1,000 pounds. Houston homes built on slabs can generally handle this without issue, but second-floor installations may require structural reinforcement. This is not something to assume — it needs to be verified by a professional before installation.
Skipping proper waterproofing around the tub surround is a recipe for hidden water damage. The area where the tub meets the wall, the wall panels above the tub, and the floor connection all need to be sealed correctly. Grout alone is not waterproofing. A dedicated moisture barrier behind the wall surface, combined with proper caulking at all transitions, is essential for a long-lasting installation.
Choosing refinishing over replacement when the tub is too far gone is a mistake we see often. Bathtub refinishing can be a reasonable option for a tub that is structurally sound but cosmetically tired. However, if the tub has cracks, chips that go through to the substrate, or drainage issues, refinishing is a band-aid, not a solution. In those cases, replacement is the smarter investment.
Not considering the drain and overflow is a subtle but important detail. If you are replacing your tub with a different model, the drain and overflow positions may not align with your existing plumbing. Addressing this during the planning phase is far easier and cheaper than discovering it during installation. At EZ Bath, we verify plumbing compatibility as part of our standard process.
Finally, neglecting ventilation leads to premature deterioration of your new remodel. Without adequate exhaust ventilation, the steam from hot baths promotes mold growth on walls, ceilings, and caulk lines. If your current exhaust fan is inadequate, a bathtub remodel is the perfect time to upgrade. View our bathtub remodel gallery for inspiration, and contact us to start your project right.
