Basement Bathroom Additions in Des Peres, Missouri

A below-grade bathroom in Des Peres has to solve three things the upstairs baths never did: drains that may sit below the sewer line, a room with no window, and a concrete floor that stays cold. We design for all three from the first sketch.

Des Peres homes and this kind of project

A basement bathroom in Des Peres means working in original ranches and the large new homes replacing them, so on our first visit we look at the rough-in stubs, the depth of the main drain and whether an ejector pit already exists.

The housing stock here: a mix of mid-century ranches and large homes built since 2000.

Mid-century houses rarely have a basement rough-in, so plan on slab cutting or an ejector basin.

Foundations and basements in Des Peres

New homes have tall basements ready to finish. Older ranches have big footprints below and need moisture and material evaluation first.

Basements under the 1950s to 1970s homes of Des Peres are usually dry and full height, and many were finished decades ago with paneling, acoustic tile and nine-inch floor tile. Those materials need testing before they are disturbed. Once cleared, the big ranch footprints give generous lower levels.

What is included

For Des Peres homeowners our basement bath scope covers drain location and camera inspection, any slab cutting and re-pour, ejector basin where needed, supply and vent piping, a ducted exhaust fan on a timer, GFCI-protected circuits, waterproofed shower walls, tile, vanity, toilet and glass.

We take on basement bathroom work in and around neighborhoods off Manchester, Ballas and Dougherty Ferry roads.

What we watch for

Ejector basins in older Des Peres finishes are sometimes unsealed or unvented, which is where sewer smell in a basement usually comes from. If you already have one, we check the lid gasket and vent connection as part of our visit.

Des Peres properties tend to be lots where coverage limits are a real constraint, and that affects how we stage materials, where a plumber, an electrician, a tile setter and a finish carpenter park and how debris leaves the site.

Permits and approvals in Des Peres

In Des Peres, a basement bathroom is reviewed by the City of Des Peres. What follows is underground plumbing, rough plumbing, electrical and final inspections.

Interior work like this normally does not involve lot-coverage and height limits, though dumpsters and working hours sometimes do, and we check.

Schedule and getting to you

Plan on three to five weeks of site work for a basement bathroom in Des Peres, once permits and materials are in hand.

Des Peres sits toward the edge of our range: I-64 to I-270 south, about forty minutes. We group trade visits and deliveries carefully for projects at that distance, and we take them on when the scope justifies a dedicated crew.

What moves the price in Des Peres

We price basement bathroom additions in Des Peres from a site visit, not a square-foot figure. These are the items that change the number.

  • Distance to the vent stack, the panel and the nearest exterior wall for the fan duct.
  • Whether a usable rough-in exists. Cutting and trenching concrete is the single biggest swing.

More detail

Our step-by-step method for this work, and the factors that move its price, are laid out on the main basement bathroom additions page. More about the area is on our Des Peres page.

Basement Bathroom Additions in Des Peres: common questions

How long does a basement bathroom take in Des Peres?

As a standalone project a basement bath usually takes three to five weeks. For Des Peres we group trade visits to keep that schedule tight despite the drive.

Who will be working in my Des Peres home during a basement bathroom?

A plumber, an electrician, a tile setter and a finish carpenter, scheduled and supervised by one Henry Hill project lead who is your single point of contact. Licensed trades are used wherever the City of Des Peres requires them.

Are sewage ejector pumps reliable?

A quality pump in a sealed, vented basin lasts many years and is quiet. We install a union and check valve so a future replacement is a short service call rather than a plumbing project.
