Basement Bathroom Additions in St. Charles, Missouri

St. Charles homes and this kind of project

Because St. Charles is made up of everything from 1800s brick to 1990s subdivisions, 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: nineteenth-century brick in the historic core, early twentieth-century bungalows and four-squares in midtown, postwar ranches, 1980s to 2000s subdivisions to the west and south, and New Town's neo-traditional homes.

Old cast iron mains under old houses need a camera inspection before we tie anything new into them.

Foundations and basements in St. Charles

Older St. Charles homes have stone or early concrete foundations with low ceilings that are better suited to dry storage than living space, and we will tell you so. Newer subdivisions have full-height poured basements that finish well. River-adjacent areas deserve extra thought about sump capacity and backup power.

Old foundations in St. Charles were built to keep a house up, not to keep a room dry. Stone and early concrete walls breathe and weep. Where ceiling height and moisture allow a finish at all, we use assemblies that let the wall dry and keep organic materials away from it. Where they do not, we say so and help you put the money into a better place.

What is included

We build St. Charles 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 St. Charles, from Frenchtown to New Town at St. Charles and midtown St. Charles.

What we watch for

In St. Charles 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.

St. Charles properties tend to be tight historic blocks near the river and ordinary suburban lots farther west, 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 St. Charles

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

Interior work like this normally does not involve historic preservation review in the old districts, though dumpsters and working hours sometimes do, and we check.

Schedule and getting to you

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

St. Charles is about half an hour east on I-70, or along Highway 370 to the north side 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 St. Charles

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

• Ejector pit and pump if gravity drainage is not available.
• Shower type: a prefabricated base with tiled walls costs far less than a fully tiled curbless shower with glass.

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 St. Charles page.
