Why Mason Remodeling Is Corona’s Preferred Bathroom Remodeling Company

Corona homeowners deal with a specific situation: thousands of 1980s to 2000s tract homes on post-tension slab foundations. Many shops price a bathroom without opening the slab or the wall, then send a change order when the framing or plumbing is worse than expected. We approach it differently. We pull enough on the front end to know what’s really there, so your written price covers the job as it actually will be built, not a hopeful guess.
Our thinking on Bathroom Remodeling follows one pattern: scope it honestly, price it in writing, and show up as the person we said we’d send. Every crew member is background-checked and identity-verified under The Threshold Standard, and you receive the technician’s name and photo before they arrive. When they knock, they carry a photo ID badge and wear a clean Mason Remodeling uniform. Isaac Pruett, who leads Mason Remodeling, built this process because a bathroom remodel means letting someone into the most private room in your house. You should know exactly who is walking in.
Corona homeowners have told us what they value most: a contractor who doesn’t disappear after the deposit, a price that doesn’t grow, and a finish they don’t have to argue about later. Our 365-Day Done Right Promise backs the work for a full year from the completion date. If something isn’t right, we return and fix it at no charge. No dispute process. No conditions to decode.
Styles & brands we work with







Shower Remodel in Corona
A shower remodel in Corona typically costs $3,000 to $12,000 depending on whether we’re replacing a shower pan and valve or taking the whole space to studs and rebuilding the waterproofing. The price range exists because a shower in a Sycamore Creek tract home on a post-tension slab often needs drain relocation, which means cutting the slab with an engineered plan and a city inspection. A shower over a raised wood subfloor costs less to modify.
Slab Work and Waterproofing
Most Corona homes built since the mid-1980s sit on post-tension slabs. Cutting into one without an engineered plan is not something any responsible contractor does. We locate the existing drain, design the new slope and drain position, and coordinate with the city before any concrete is touched. The waterproofing underneath matters just as much: we use Schluter systems and do a 24-hour flood test before tile goes in.
Valves, Niches, and Glass
We default to pressure-balanced valves from Moen, Kohler, or Grohe because they hold temperature steady when someone flushes a toilet elsewhere in a Corona home. A framed niche, built to your tile layout rather than dropped in randomly, costs little but changes how the shower feels. Frameless glass enclosures run higher than curtain rods but open up a small hall bath in older south Corona houses.
Tub to Shower Conversion in Corona

A tub-to-shower conversion in Corona costs $3,500 to $10,000, and in this city the big cost driver is almost always the drain. Tubs sit on 1.5-inch drains. Showers require 2-inch drains under California code. In a post-tension slab home, widening that drain means cutting the slab with an engineered plan, repositioning the p-trap, and passing an inspection before the concrete is patched. That’s real work, and we price it from the start.
What the Conversion Includes
A conversion in a typical Corona home means removing the tub, re-routing the drain to 2 inches, building the shower pan or installing a low-profile acrylic base, waterproofing the walls, and setting tile, fixtures, and glass. We handle the permit, the inspection, and the coordination with the city. When the framing behind the old tub shows moisture damage, as it often does in 25-year-old tract homes, we repair it before waterproofing goes in.
Why Homeowners Convert
People in Corona convert tubs to walk-in showers for one of three reasons: aging in place, taller family members who never use the tub, or a desire to open up a small bathroom visually. A curbless entry adds cost and usually needs more slab work, but it’s the right call for mobility. We’ll walk through the options and give you a written line-item price for whichever route fits.
Trusted Brands We Service in Corona
We install and service the brands Corona homeowners ask for by name: Kohler, Moen, and Toto fixtures, Cambria, Silestone, and Caesarstone surfaces, plus KraftMaid and Wellborn cabinetry. Because we work with specification-grade lines and have standing partnerships with distributors that serve the Inland Empire, we can source materials fast for Corona projects. Dvele and Cover show up occasionally as reference points from homeowners exploring prefab builds or ADU designs in Horsethief Canyon and Eagle Glen. The practical advantage for you: one contractor handles the plumbing, tile, glass, vanity, and fixtures instead of three subs who don’t talk to each other.

AfterCommon Bathroom Remodeling Problems We See in Corona Homes
- Post-tension slab surprises. A builder who doesn’t x-ray or use the original tensioning plan before cutting a slab can damage the tendons that keep the foundation stable. In Corona’s 1980s-2000s tract home stock, this is the single most expensive mistake we’re called in to fix after another contractor walks off the job.
- Moisture behind 30-year-old tile. Grout cracks, caulk joints open, and water gets behind the wall. By the time a homeowner sees staining or smells mildew, the hardiebacker or drywall behind the tile is often compromised. We open the wall, repair the framing, and rebuild the waterproofing correctly.
- Undersized drain lines on tub-to-shower conversions. The original 1.5-inch tub drain cannot legally or practically handle a 2-inch shower requirement. Skipping this upgrade causes slow draining and a code violation that surfaces at resale.
- Builder-grade allowances that trap homeowners. A quote with a vague “tile allowance” or “fixture allowance” often prices the lowest possible option. When you choose the Kohler valve and porcelain tile you actually want, the bill grows. We quote actual materials by name and model where possible, and we put it in writing before work starts.

We recently finished a hall bath in the Sycamore Creek area of south Corona, taking it down to studs for a tub-to-shower conversion: new pressure-balanced Moen valve with rough-in, a framed niche, and 12×24 porcelain over a Schluter waterproofing system. The original 1990s copper stub-outs needed re-routing, and our tech found early subfloor moisture near the toilet flange that we handled with new hardiebacker and a sealed flange before tile. Final walk on the punch list included a 24-hour flood test and city inspection sign-off. That’s the standard we hold on every Corona job.

FAQs About Bathroom Remodeling in Corona
Yes, in almost every case. Any work that moves a drain, alters plumbing, adds a valve, or changes electrical wiring requires a permit through the City of Corona’s building department. We pull the permits, schedule the inspections, and make sure the final sign-off is in place. Skipping permits might save a few hundred dollars now, but it creates a resale problem later and it’s not a shortcut we’ll take.
A full bathroom remodel in Corona runs $9,000 to $28,000. Small bathrooms run $5,000 to $12,000. A tub-to-shower conversion is $3,500 to $10,000, and a walk-in shower install is $4,500 to $12,000. The spread comes from slab work, fixture choices, tile specs, and whether we’re moving plumbing. Call (803) 680-2547 and we’ll give you a written line-item price for your exact project.
Nothing, if the scope was written correctly. The change orders that blow up budgets in Corona usually come from wall or slab conditions that weren’t examined before the quote was given. We scope before we price, which means opening access panels, checking the drain size, and testing for moisture where it matters. If you authorize a change mid-project, we price it and get your written approval before doing the work. The price never grows on its own.
Yes, and we do it regularly in 1980s-2000s tract homes on post-tension slabs. The conversion is legal and common, but it requires widening the drain from 1.5 inches to 2 inches under California code. In a slab home, that means cutting the concrete with an engineered plan and passing a city inspection. We handle all of that, and the cost is included in the written quote up front. Curious what it would cost in your specific house? Call (803) 680-2547 for a free estimate.
Most full bathroom remodels in Corona take two to four weeks, depending on slab work and inspection scheduling. A tub-to-shower conversion typically runs one to two weeks. The city inspection calendar affects the timeline, and we schedule inspections as early as possible to keep things moving. We’ll give you a written timeline with your quote.
