Fiberglass tub-and-shower combos are one of the most common setups in Houston homes built from the 1980s onward. They are inexpensive to install during new construction, which is why builders love them. But after years of use, they yellow, crack, and become a cleaning nightmare. If you are ready to replace your fiberglass tub with a modern walk-in shower, here is what the process looks like and what to consider.
The first step is a professional assessment of your bathroom. A design consultant will measure the space, inspect the existing plumbing, and discuss your preferences for the new shower layout. The footprint left by a standard 60-inch tub is perfect for a spacious walk-in shower, so you typically do not need to expand the room. The key decisions at this stage are the wall material, shower base, fixture style, and glass door configuration.
Demolition involves removing the fiberglass unit, which usually comes out in sections. The surround panels are cut and pulled away, then the tub basin is disconnected from the drain and lifted out. Once the fiberglass is removed, the crew inspects the wall framing and subfloor for any water damage or mold — both of which are common behind old fiberglass units. Any damage found is repaired before the new installation begins.
Plumbing modifications are typically needed when converting from a tub to a shower. The shower valve needs to be repositioned to the correct height, and the drain may need to be relocated or resized. Tubs use a 1.5-inch drain while showers generally require a 2-inch drain for adequate water flow. A professional tub-to-shower conversion includes all necessary plumbing work to ensure everything functions properly.
The new shower base is installed next. Options range from acrylic bases to solid surface custom pans. Solid surface bases from the Onyx Collection are a popular choice because they are custom-made to fit your exact dimensions, slip-resistant, and available in colors that coordinate with the wall panels. The base is leveled, secured, and sealed to create a watertight foundation.
Wall panels go up after the base is set. Solid surface panels install with construction adhesive directly to the prepared wall surface and interlock at the seams for a waterproof fit. The result is a smooth, grout-free surface that cleans with a simple wipe. Fixtures are mounted, the glass door or enclosure is installed, and the final caulking and trim work complete the project.
Most fiberglass tub-to-shower conversions are completed in two to three days, and the difference is remarkable. Where there was once a yellowed, cramped tub that nobody wanted to use, there is now a bright, open shower that feels like it belongs in a brand-new home.
