Sterling Bathroom Remodeling: The Riverside Owner’s Guide
We replace and remodel Sterling bathroom components throughout Riverside, which typically runs $9,000 to $28,000 depending on the scope, from a tub-to-shower swap to a full tear-out with new tile and fixtures. Most owners call us when one part, a cracked shower pan, a worn cartridge, a leaking surround, has finally pushed them over the edge. The part failed, but the fix usually means more than replacing that one piece. Often the surrounding waterproofing gave out right behind it, and nobody knows until demo starts.
If you’re holding a failed Sterling part and wondering whether it can be matched and fixed fast, this page lays out what we stock, what we replace, what it costs in Riverside, and when it’s smart to just replace the whole unit rather than patch a losing battle. Trevor Nash has spent nearly two decades on construction across the Inland Empire, and the crew has put real hours into older Riverside homes, including the Arlington neighborhood, where houses have a way of keeping you honest about what’s behind the walls.
Which Sterling Models This Applies To

Sterling builds three main lines we see in Riverside bathrooms: the Vikrell solid-surface tubs, shower bases, and surrounds; the Ensemble and Accord bathtub-and-wall kits; and the Performance series of shower receptors and drains. The model number is usually molded or printed on a label under the tub deck or behind the front apron near the drain side. It’s worth taking a photo of it before you call, because a Vikrell surround from 2012 does not always interchange with the 2024 version even when they look identical from across the room.
One compatibility gotcha we run into constantly in Riverside: older Sterling shower bases were sized for a 60-inch rough opening, but newer Performance series bases are designed for a slightly tighter 60-1/4-inch framed opening. If you buy a current base for an older home, you may find yourself shimming and furring the studs to make up a quarter inch. We’d rather catch that before the base arrives.
When it comes to OEM versus aftermarket: for finish trim and drain assemblies, quality aftermarket equivalents from suppliers like Jones Stephens or Dearborn work fine and can cut part cost by 30 to 40 percent. For the tub or shower base itself, we only buy OEM Sterling. A Vikrell base is compression-molded in one shot, and when aftermarket “universal” pans crack or flex, the warranty rarely follows the homeowner. Penhallow Remodeling Riverside is an independent contractor, not affiliated with Sterling. We just know their parts because we’ve pulled enough of them apart.

Signs Your Sterling Bathroom Remodeling Is Failing
- Hairline cracks in the tub or shower floor. Vikrell is tough, but a flexing subfloor or a settled floor joist can stress the base until it cracks along the drain channel. The crack is the symptom; the flex underneath is the problem.
- Water staining on the ceiling below the bathroom. That usually means the drain gasket or the rubber seal under the waste assembly has dried out and is dripping during every shower, not just a failed seal at the visible drain ring.
- Soft or spongy spots at the bottom of the surround walls. Water has wicked behind the surround and saturated the drywall or greenboard behind it. Once the substrate, the surface layer behind your wall panel, turns to chalk, the surround will start pulling away from the studs.
- Trim plate and valve cartridge failures. Sterling’s pressure-balance cartridges are generally reliable, but Riverside’s hard water shortens their life. If the handle starts sticking or you can’t hold temperature steady, the cartridge is on its way out, and replacing it beats waiting until you have no shower at all.
- Persistent mildew odor that never goes away. When water has been pooling behind a surround or under a base for months, the smell outlasts the bleach. By then the right fix is removal and inspection, not another scrub.
Replacement Cost & What’s Included

A full Sterling bathroom remodel in Riverside, one that pulls the old tub or shower, addresses the substrate and waterproofing, and installs a new Sterling unit with tile, trim, and fixtures, lands between $9,000 and $28,000. Where the number falls depends on three things: whether the existing framing and plumbing are salvageable, the size and finish level of the new Sterling components, and whether you’re keeping the existing floor plan or changing it.
A tub-to-shower conversion with a new Sterling Vikrell base and surround typically runs at the lower end of that range. If we’re reworking drain placement, replacing a rotted subfloor, moving a wall, or adding tile work and a glass enclosure, the price climbs. Every estimate we write in Riverside includes the parts, the labor, the debris hauling, and the waterproofing line by line. There’s no vague “miscellaneous” line. The number we hand you before we start is the number on the invoice. That’s how we work, and the 365-Day Done Right Promise backs it in writing.

You can safely check a few things yourself: take a photo of the model label, note the size of the rough opening, and look for obvious cracks around the drain. That information makes the first call shorter and the eventual quote more accurate. Replacing a cartridge or a showerhead is a reasonable Saturday job for a confident homeowner with the right cartridge on hand.
Removing a tub or shower base is a different animal. The base is glued to a mortar bed, the drain is sealed from below, and the surrounding walls almost always hide water damage once you open them. If you’re working around the drain trap, you’re also working near the P-trap and waste line, and a wrong connection means a slow leak behind a finished ceiling. We’ve repaired plenty of DIY demolitions where the original $200 part became a $2,000 water damage claim. If you want a number before you touch anything, call us at (341) 895-1170. Give you a number before we pick up a tool, that’s just how this works.
FAQs

A properly installed Sterling Vikrell tub or shower base typically lasts 20 to 30 years in Riverside’s climate, though Riverside’s hard water and the summer heat cycles in unconditioned bathrooms can shorten the lifespan of cartridges, seals, and caulk joints significantly. If your unit is over 15 years old and showing multiple symptoms from the list above, replacement is usually the better financial decision. Call (341) 895-1170 for an honest assessment and a free estimate, and we’ll tell you if a repair is worth your money.
Surface repair kits can patch a crack temporarily, but a cracked base almost always means the mortar bed or subfloor underneath is flexing, and the crack will return. We don’t recommend patching a Sterling base that’s actively leaking, especially into a ceiling below, as the repair puts your home at continuing water damage risk. Call (341) 895-1170 and we’ll give you a no-pressure quote on replacing it right.
A standard tub-to-shower conversion in Riverside takes three to five working days from demo to final caulk, assuming the framing and plumbing underneath are sound. If we uncover water damage or need to move drain lines, add a day or two, and we’ll tell you before the work starts. Call (341) 895-1170 for a written schedule and a firm price.
We stock common Sterling cartridges, drain assemblies, trim kits, and surrounding seal kits on our service vehicles, and we can usually source OEM Vikrell bases and surrounds from local Riverside plumbing suppliers within a couple of days. If the part is discontinued or backordered, we’ll tell you the expected wait time before you commit to anything. Call (341) 895-1170 with your model number and we’ll check availability on the spot.
