Basement Bathroom Additions in Weldon Spring, Missouri

Weldon Spring homes and this kind of project

Because Weldon Spring is made up of custom homes on an acre or more and the estates of Whitmoor, the first thing we check for a basement bathroom here is the rough-in stubs, the depth of the main drain and whether an ejector pit already exists.

The housing stock here: custom homes from the 1970s onward on large lots, golf community estates and recent luxury construction.

In larger homes a lower-level bath is often a full guest bath with a tiled curbless shower and heated floor.

Foundations and basements in Weldon Spring

Sloping lots give many Weldon Spring homes full walkout lower levels with real windows and doors. They finish beautifully, and owners often want a second kitchen, a guest suite and a theater. Hillside drainage has to be right before any of that goes in.

Lower levels in Weldon Spring's larger homes are full floors, often walkouts of two thousand square feet or more. Owners finish them to the same standard as upstairs, with a bar or second kitchen, guest suite, gym and theater. Proper zoning of heating and cooling for a space that size is part of the design.

What is included

We build Weldon Spring basement bathrooms as standalone projects or as part of a full finish. Either way the underground plumbing gets inspected before concrete goes back, and the shower gets a flood test before tile.

We take on basement bathroom work across Weldon Spring, from the Highway 94 and Wolfrum Road area to Whitmoor Country Club and Weldon Spring Heights.

What we watch for

Ejector basins in older Weldon Spring 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.

Working on rolling, wooded sites with real slope, as we do in Weldon Spring, we plan access for a plumber, an electrician, a tile setter and a finish carpenter before the first delivery arrives.

Permits and approvals in Weldon Spring

In Weldon Spring, a basement bathroom is reviewed by the City of Weldon Spring or St. Charles County, depending on the parcel. What follows is underground plumbing, rough plumbing, electrical and final inspections.

Being inside the house, this project is unlikely to need sign-off from gated-community and subdivision architectural review, but we confirm any rules on containers and work hours.

Schedule and getting to you

Most Weldon Spring clients see three to five weeks of construction for a basement bathroom.

Weldon Spring is down I-64 to Highway 94, a little over twenty minutes from our Wentzville base. We plan crew days and deliveries around that drive so you get full working days on site.

What moves the price in Weldon Spring

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

• Shower type: a prefabricated base with tiled walls costs far less than a fully tiled curbless shower with glass.
• Distance to the vent stack, the panel and the nearest exterior wall for the fan duct.
