Converting a bathtub alcove to a shower changes the wet-area assembly, drain relationship, access and finished floor height. It should be planned as a shower reconstruction, not just removal of the tub.
Existing Tub Area
The first step is documenting:
- alcove width and depth;
- tub type;
- drain location;
- plumbing wall;
- existing tile or surround;
- subfloor condition;
- desired entry height;
- enclosure type.
Demolition can reveal water damage or framing conditions that affect the plan.
Drain and Plumbing
A shower may require a different drain position or configuration from the existing tub.
Drain relocation, trap or waste changes, valve changes and supply piping should be handled by qualified plumbing professionals.
Shower Base and Waterproofing
The new shower needs a complete compatible pan and waterproofing system.
Prefabricated bases, site-built systems and tiled pans have different requirements. Mixing incompatible membranes, drains and backers should be avoided.
Accessibility Goals
A lower threshold, grab bars or wider access can be part of the design goal.
Specific accessibility or code claims should not be made unless the design has been reviewed against the applicable requirements.
Tile and Enclosure
After the wet-area system is complete, tile or wall panels and the enclosure can be installed.
Glass size and door swing depend on final finished dimensions.
FAQ
Can the drain stay where the tub drain is?
Sometimes, but the shower design and plumbing requirements determine that.
Can the conversion be curbless?
A curbless shower can require floor recess, structural work, slope and waterproofing changes and should be designed appropriately.
Does the project include plumbing?
Qualified plumbing professionals should handle plumbing-system changes.
Can grab bars be added?
Potentially, when suitable structural backing and the chosen product are provided.
