Basement Bathroom Additions in Cottleville, Missouri

Cottleville homes and this kind of project

A basement bathroom in Cottleville means working in newer custom and semi-custom homes, 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: newer custom and semi-custom two-stories and one-and-a-half stories, villa communities, and a handful of older homes in the original village.

Newer homes nearly always have a clean rough-in, which keeps this project modest.

Foundations and basements in Cottleville

Basements in Cottleville's newer homes tend to have nine-foot pours, which makes a big difference: ductwork can be boxed without the ceiling feeling low. Many were plumbed for a bar as well as a bath. These are ideal candidates for a lower level that matches the main floor in quality.

Newer homes in Cottleville come with clean, tall, dry basements, a bath rough-in and a sump, and no previous work to undo. Finishing them is efficient. The main decisions are layout, how much to invest in a bath and bar, and ceiling treatment around the ductwork.

What is included

For Cottleville 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 across Cottleville, from the Village at Twin Creeks area to neighborhoods along Highway N and Weiss Road and Old Town Cottleville.

What we watch for

In Cottleville we often find rough-in stubs that were bumped or filled with debris during original construction. We clear and test them before design, because discovering a blocked drain after the vanity is in is nobody's idea of a good day.

Working on larger lots in recently built subdivisions, as we do in Cottleville, we plan access for a plumber, an electrician, a tile setter and a finish carpenter before the first delivery arrives.

Permits and approvals in Cottleville

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

Being inside the house, this project is unlikely to need sign-off from active architectural committees that expect materials to match the house, but we confirm any rules on containers and work hours.

Schedule and getting to you

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

Cottleville is down I-64 and across on Highway N, a bit 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 Cottleville

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

• Whether a usable rough-in exists. Cutting and trenching concrete is the single biggest swing.
• Ejector pit and pump if gravity drainage is not available.
