Fast, Reliable Bathroom Remodeling Across Crestline
Bathroom remodeling in Crestline typically runs $9,000 to $28,000 for a full gut and rebuild, with smaller jobs like a shower replacement or vanity install landing between $800 and $12,000 depending on scope. Most Crestline homes are mid-century mountain cabins and lake cottages, which means the real work usually starts below the tile – in the subfloor, the joists, and the drain lines.
If you’re planning a bathroom remodel in Crestline, you need a contractor who understands what sixty-year-old mountain framing does after decades of snow load and seasonal moisture. Our Bathroom Remodeling team has opened enough Crestline walls to know what’s behind them. Call (803) 680-2547 to schedule a free estimate. We’ll put the price in writing before any work starts.
Why Mason Remodeling Is Crestline’s Preferred Bathroom Remodeling Company

Crestline homeowners call us because we don’t bid a bathroom off photos and hope for the best. Isaac Pruett leads our team with a straight-ahead approach: open the floor, look at the framing, tell you what we found, and price it in writing. No verbal ballparks that balloon later. No surprises on the final invoice.
Every crew member who comes to your Crestline home is background-checked and identity-verified under the Threshold Standard. Before the visit, you receive the technician’s name and photo. At the door, they show a photo ID badge and arrive in a clean marked uniform. You know exactly who is walking into your home before they step on the porch. That matters whether you’re home alone, managing kids, or just don’t want strangers in your house.
Our clients in Crestline tell us the same thing after the job: the written price was the price. That’s because we deliver a fixed, line-item estimate before any tool is unpacked, and we stand behind the finished work for 365 days under the Done Right Promise. If something isn’t right within a year of completion, we fix it at no cost to you. It’s that simple, and it’s written into every contract.
Styles & brands we work with







Small Bathroom Remodel in Crestline
A small bathroom remodel in Crestline usually means working with 35 to 60 square feet of floor space, a 5-foot wall, and a toilet flange that’s been sitting in the same spot since the Kennedy administration. These jobs run $5,000 to $12,000 depending on what we find when the old materials come out. If you’re in a cabin near Lake Gregory or up in the Valley of Enchantment area, expect the price to lean toward the higher end once we sister the joists and replace the rot.
What the Job Actually Involves
We pull the old flooring, vanity, and fixtures down to the framing. In Crestline cabins, this is where the real scope reveals itself. Undersized joists, spongy subfloor, cast-iron drain pipes that have outlived their service life. We fix all of it before we lay a single tile, because new tile over a soft floor is just an expensive way to buy the same problem twice.
When the Layout Has to Change
Sometimes the stock vanity you ordered won’t clear the toilet flange, or the shower valve is roughed in 2 inches off where the new tile needs it. We handle this during the rough-in phase, before drywall goes up, so you’re not paying for a change order in week four. Isaac Pruett reviews every Crestline small bathroom layout against the actual framing before we order materials.
Shower Remodel in Crestline

A shower remodel in Crestline runs $3,000 to $12,000 depending on whether you’re replacing an existing unit, converting a tub, or building a walk-in from scratch. The lower end covers a like-for-like shower replacement. A full walk-in shower installation with a Schluter-Kerdi waterproofing system, new valve, and tile work lands in the $4,500 to $12,000 range. Mountain moisture makes waterproofing the single most important decision in any Crestline shower project.
Working With the Wall You Have
We frame and waterproof for the specific wall conditions in your cabin. Plaster over lath, drywall over studs, whatever’s there. The goal is a shower that doesn’t leak through to the room below in three years. In a Crestline cabin, that means a full waterproof membrane, not just green board and hope.
Valves, Trim, and Finish Details
We install Kohler and Moen valves and trim as standard. We also set the Schluter strip – the metal trim that seals the edge where tile meets flooring – so the finished shower looks intentional, not patched. If you’re upgrading a tub to a walk-in, we handle the plumbing rough-in, the pan, the glass enclosure, and the inspection sign-off.
Trusted Brands We Service in Crestline
We install and work with specification-grade fixtures and surfaces across the board – Kohler and Moen in the shower, KraftMaid and Wellborn for cabinetry, Cambria and Silestone for solid surfaces. We don’t push whatever’s on the shelf at the supply house. We order what fits your bathroom’s dimensions and your home’s structure. Because we stock common parts locally for Crestline customers, turnaround on a vanity swap or fixture change stays tight. If the job calls for a specific line from Toto or Grohe, we’ll source it and handle the install with the same written price and the same 365-day guarantee. We’ve also seen enough factory-built ADU and prefab cabin shells in the mountain communities, like Abodu and Cover, to know how to integrate a bathroom remodel into a modern prefab without fighting the existing plumbing design.

AfterCommon Bathroom Remodeling Problems We See in Crestline Homes
- Sagging wood-framed subfloors. Mid-century mountain cabins were framed with joists sized for a different world. Add decades of seasonal moisture, and the floor moves when you walk on it. We sister the joists and replace the subfloor before any tile goes down.
- Hidden rot around tubs and toilets. A toilet that rocks or a tub that creaks usually means the framing underneath has been wet for years. Opening the floor reveals it. Bidding without opening it hides it. We open first, then price.
- Cast-iron drain lines at the end of their life. Crestline homes built before 1975 often have original cast-iron drainage. When we open the wall for a valve or shower change, we inspect what’s there and tell you if it needs replacement now or can wait.
- Vanities that don’t fit the 5-foot wall. Flatland tract homes have predictable bathroom dimensions. Crestline cabins don’t. We measure the actual wall, the actual toilet flange location, and the actual door swing before we order a single cabinet.

FAQs About Bathroom Remodeling in Crestline
Yes, for most bathroom remodels in Crestline that involve moving plumbing, changing a shower valve, or altering framing. Crestline falls under San Bernardino County jurisdiction, and the county requires permits and inspections for any rough-in plumbing or structural work. We pull the permits, schedule the inspections, and make sure the job passes before we close the walls. A bathroom remodel without a signed-off rough-in inspection can become a problem when you sell. Call (803) 680-2547 and we’ll walk you through what applies to your specific scope.
Online calculators assume a flatland tract home with a stable subfloor and newer plumbing. Crestline homes are mountain cabins with wood-framed subfloors, aging cast-iron drains, and joists that were undersized when they were framed sixty or seventy years ago. When you open the floor, you find rot and movement that no online quote ever accounted for. That’s why we open first, then price. A $9,000 small bath remodel can become $12,000 once we sister the joists – but you’ll know that before we start, not after. Free estimates: (803) 680-2547.
No, and you shouldn’t trust anyone who will. Photos can’t show what’s under the vinyl floor or behind the shower surround. In Crestline, the subfloor is the entire game. We’ll give you a detailed written estimate after we walk the home and open the areas that matter, then the price is fixed. No change orders for things we should have seen. That’s the whole point of the written price before work starts.
A small bathroom remodel in Crestline typically takes 3 to 4 weeks from demo to final inspection. A shower replacement or vanity install is faster – often 1 to 2 weeks. A full bathroom remodel with a walk-in shower, new framing, and a drain line replacement can run 5 to 6 weeks. Weather matters up here. Snow and ice on Highway 18 or 138 can delay deliveries and inspections, so we build that into the schedule and keep you informed. We don’t rush the waterproofing or the inspection sign-off.
We don’t ask for full payment upfront. The schedule is tied to milestones: a deposit to lock the schedule and order materials, a draw at rough-in completion, a draw at drywall and tile completion, and the balance after final inspection. Every draw is spelled out in the written contract before work begins. Call (803) 680-2547 and Isaac Pruett will walk you through the exact numbers for your project.
