The upgrade that makes a basement truly livable

A finished basement feels great until someone needs to use the restroom and has to climb the stairs. Adding a bathroom solves that, and it changes how your family uses the space. A guest room becomes a real guest suite. A rec room becomes a place people can spend the whole evening. A future rental unit finally meets code. For most homeowners, the bathroom is the piece that turns a nice basement into a complete second level.

We build bathrooms to match how the room will be used. A simple half bath works for a family rec area, while a full bath with a walk-in shower fits a guest suite or apartment. We help you pick the right layout for your space and your budget before any work starts.

What the work involves

Basement bathrooms take more planning than bathrooms on upper floors because the plumbing sits at or below the main sewer line. Here is what a typical project includes:

  • Plumbing. We connect to an existing rough-in when one is there. When it is not, we cut the slab, run new drain and supply lines, and patch the concrete.
  • Framing and waterproofing. We frame the walls, set the shower base or tub, and waterproof wet areas the right way.
  • Tile and fixtures. Shower tile, flooring, a vanity, a toilet, a mirror, and the lighting that pulls the room together.
  • Ventilation. A vent fan ducted outside keeps moisture in check, which protects your finished basement from mold and damage.
  • Ejector pump when needed. If the bathroom sits below the sewer line, we size and install a pump so waste drains correctly.

What a basement bathroom costs

Most basement bathrooms run about $9,000 to $18,000. The biggest factor is plumbing. If your builder left a rough-in, the price stays near the lower end. If we need to cut concrete and run new lines, it moves up. Tile choices, fixtures, and whether you want a half bath or a full bath with a shower also shape the final number. See how this fits into a full project on our pricing section, and learn how a bathroom supports a rental on our basement apartment and ADU page.

Basement bathroom questions

Yes. When there is no existing rough-in, we cut the concrete, run new drain and supply lines, then patch the slab before framing. It adds cost and a little time, but it is a common and routine part of the work.

Yes. Every basement bathroom needs a vent fan ducted to the outside to control moisture and keep the space healthy. Some setups below the sewer line also need an ejector pump, which we size and install as part of the job.
