A Master Bathroom That Was Due for More Than a Refresh

This Temecula master bathroom renovation started as a surface-level update a new vanity, updated lighting, fresh mirrors. The kind of cosmetic refresh many homeowners plan when a bathroom starts to feel dated.

But when Daniel Nikolic and the team began opening up the shower area, what they found changed the entire project. Black mold was growing behind the shower wall, and moisture had been leaking into the plywood subfloor – a telltale sign the original hot mop waterproofing had failed years earlier.

Rather than working around the problem, Nikolic Construction rebuilt the shower from scratch: removing the wall, installing Schluter KERDI waterproofing membrane, tiling two walls with large-format tile, and replacing the enclosed shower with a frameless glass enclosure and ceiling-mounted rainfall showerhead.

Frequently Asked Questions: Master Bathroom
Renovation in Temecula

How much does a master bathroom renovation cost in Temecula?

Master bathroom renovations in Temecula typically range from $15,000 to $50,000+ depending on the scope. A full remodel including shower rebuild, freestanding tub, new vanity, tile work, and mold remediation – like this project – is a substantial investment that delivers significant ROI at resale. Nikolic Construction provides free, written estimates with no pressure. Call (951) 239-4205 to schedule yours.

What is black mold and is it dangerous in a bathroom?

Black mold in a bathroom is typically caused by prolonged moisture exposure – often from a failed waterproofing layer like a hot mop. It can affect indoor air quality and, in larger concentrations, respiratory health. The most important thing is not to tile over it. The mold must be fully removed, the moisture source corrected, and the area dried before any new materials are installed. That’s exactly what Nikolic Construction did on this Temecula renovation.

What is a hot mop and why did it fail?

A hot mop is a traditional waterproofing method applied beneath shower floors and walls. Over time – especially in older Temecula homes – hot mops can crack, shrink, or fail, allowing water to penetrate into the subfloor and framing below. On this project, the leak was visible in the saturated plywood beneath the shower. Nikolic Construction replaced it with Schluter KERDI membrane, a modern, superior waterproofing system with a much longer lifespan.

Is a freestanding tub a good choice for a master bathroom renovation?

A freestanding soaking tub is one of the most impactful upgrades in any master bathroom renovation. It immediately elevates the visual quality of the space and is a strong selling point with homebuyers. It also frees up wall space and allows more flexibility in layout. On this Temecula project, the freestanding tub replaced a dated built-in and completely changed the feel of the room.

How long does a full master bathroom renovation take in Temecula?

A full master bathroom renovation – including demo, mold remediation, waterproofing, tile work, fixture installation, and vanity replacement – typically takes 3 to 6 weeks depending on the scope and any unexpected discoveries. Nikolic Construction provides a realistic written timeline upfront and keeps homeowners informed throughout the project.
