What Does It Cost to Add a Half-Bath?

Besides remodeling your kitchen, adding a half-bath or remodeling your bathroom are two of the most popular home improvement projects. Both provide a wise investment, with homeowners seeing an average 60 percent ROI when it’s time to sell.

Location

Two main considerations for placing your half-bath are space and privacy. Most half-baths need at least three to four feet in width and six to eight feet in length. It’s best to place it in a private area, away from the direct line of sight of living or dining areas. If you have a hallway or under-stair space, that can be an ideal location.

Plumbing

Plumbing is often the biggest cost for a half-bath addition. Homes with a basement or pier-supported foundation make it easier to run plumbing lines. But for homes with a slab foundation, more labor is required to run pipes through the floor. To save costs, place the half-bath near existing plumbing.

Amenities

Your half-bath should include a toilet, sink, and mirror. If you have extra space, you can add a vanity or storage cabinet. For homeowners looking to increase resale value, consider adding a shower to turn the half-bath into a three-quarters-bath.

Ventilation

Proper ventilation is a must, according to building codes. This can be accomplished by installing an exhaust vent or having an operable window.

Electrical

You’ll need to install ground fault circuit interrupter (GFI) outlets to protect against electrical shock, especially since water sources like sinks are nearby. This is a standard requirement for safety in bathrooms.
