Embarking upon a bathroom project can be a pretty daunting prospect. Which is why it pays to arm yourself with knowledge before you begin.

We’ve worked with to create a series of “ask the experts” blog posts, where we pick out the most commonly asked questions about bathrooms and let experienced and recommended professionals provide you with the answers.

In this article, we’ll looking at conversion projects and answering the question: “Can I convert an upstairs bedroom into a bathroom?”

Can I convert an upstairs bedroom into a bathroom?

Any room can be turned into a bathroom, but some will be easier than others. There are a few key considerations—where the property’s soil stack (the pipe which removes waste water from the upstairs of a building) is located, how the current hot and cold water supplies are arranged, and how the room itself is structured, including the orientation of the floor joists.

Lambert Plumbing & Heating Ltd state: “There shouldn't be any reason why not. Most problems can be overcome, i.e. if you are some distance from your soil stack, your waste could be pumped by a Saniflo product. A bedroom can be tiled and tanked (waterproofed) just as well as any bathroom!”

Fitting your toilet


As the experts at Lambert Plumbing & Heating Ltd mention, just about any space can be turned into a bathroom, even if it’s a fair distance away from the soil stack, using a Saniflo product.

Saniflo are one of the leading names in sanitary treatment products, which includes waste pumps and macerators.

What is a macerator?

Put simply, a macerator is a unit, powered by electricity, which can be attached to a toilet, basin, bath, shower (or a combination of all of these). Using a grinding or blending mechanism, it reduces solid waste to a liquefied form so it can be moved by small bore pipes to your soil stack.
