Transforming Utility into Luxury
A luxury bathroom is arguably the most complex room in the house per square foot due to the density of water lines, electrical outlets, and ventilation systems. High-end bathroom fabrications in the Baltimore area operate with a starting baseline of $25,000+.
The difference between a standard bathroom contractor and a high-end design-build firm lies in the waterproofing technique and the substrate engineering.
Substrate Engineering
Laying massive format stone tiles or executing a seamless curbless shower requires a perfectly level subfloor. A deflected joist will crack a luxury marble floor in a matter of months. Prime Renovations actively reinforces the joist structure before laying specialized, monolithic waterproofing membranes beneath the tile surface.
Nothing is left to chance. Every finish is meant to be permanent. Read more about how Prime Renovations executes flawless bathroom models on our Capabilities Page.
Common questions
Why does a luxury bathroom cost more per square foot than other rooms?
It concentrates water supply, drains, electrical, ventilation and waterproofing into a small footprint, and large-format stone or a curbless shower depends on a perfectly flat, stiff subfloor. High-end bathroom builds in the Baltimore area start around $25,000.
What is a curbless shower and what does it require?
A shower whose floor is flush with the bathroom floor, with no threshold. It needs the subfloor recessed or the joists adjusted so the shower pan can slope to the drain, and a continuous waterproofing membrane installed to the tile industry's ANSI A118.10 standard.
Will large marble tiles crack on a wood-framed floor?
They can if the joists deflect. Prime reinforces the joist structure and installs a monolithic waterproofing membrane before tile so the stone stays sound.
