Tub-to-Shower Conversion in Columbia, MD

The reason we hear most often is the step. A standard tub wall is 15 to 18 inches tall, and that height stops being a small thing after a knee replacement or a bad winter on the ice. The second reason is space: pulling a tub out of a 60 inch alcove gives you a shower that is 30 inches deep instead of the 22 inch strip you had standing at one end of a tub. The third is maintenance, since old tub surrounds hide water damage you cannot see until the drywall outside the shower goes soft. Cleaning is the quiet one: sliding tub doors run on a bottom track that never comes clean, while a single glass panel with no track wipes down in a minute.

Opening the Wall

The surround comes off down to the studs. This is where rotted framing, soft subfloor, and old galvanized pipe show up, and we photograph and price any repair before we carry on.

Plumbing the New Shower

The tub drain moves from the end of the alcove to the center of the new pan, and the valve gets reset at standing height with a mixing valve so a flushing toilet does not change your water temperature.

Framing and Blocking

Niches, a bench, and grab bar blocking all get framed before tile. Adding any of them later means cutting a finished wall open, so we ask about them at the walkthrough.

Pan, Membrane, and Tile

A sloped mud bed goes down, a bonded waterproofing membrane goes over it and up the walls, and the tile goes on top of that. Glass is measured after the tile is finished and set about a week later.

Your Shower Floor Options After the Tub Comes Out

The pan decides how the shower drains, how it feels underfoot, and how much framing work the job needs. Three choices cover almost every Columbia bathroom.

A tiled mud-set pan is the most flexible. We slope it by hand about a quarter inch per foot, so it works in odd shaped alcoves and lets the floor tile carry into the shower for a continuous look. Small format tile or hex mosaic gives the grout lines enough grip for wet feet.

A solid surface or acrylic base drops in as one piece with no grout at all. It is the fastest to install and the easiest to keep clean, and it makes sense in a rental or a bathroom that gets hard daily use.

A low-curb pan sits two to three inches off the floor instead of the four inches a standard base needs. Second floor framing in most Columbia townhomes will not allow a fully flush pan, so this is usually as close to curbless as the house will go.
