Tub-to-Shower Conversion Cost in Denver

Pulling out a tub and replacing it with a shower is one of the most common requests we get in Denver bathrooms, and it is also one of the projects where the quotes homeowners collect vary the most. One contractor says $3,000, another says $15,000, and both of them might be right, because they are describing two different projects. Tub to shower conversion cost in Denver runs anywhere from $2,500 to $20,000 depending on what you build in the tub's place and what the crew finds when the tub comes out. By the end of this article you will know which tier your project falls into, what the hidden costs usually are in older Denver houses, and where the real money goes.

The three cost tiers for a conversion

The simplest version of this project is a prefab shower unit set into the existing tub alcove. The tub comes out, the drain gets adapted, the valve gets replaced, and a one-piece or multi-piece acrylic surround goes in where the tub used to be. Nothing moves. In Denver that runs $2,500 to $5,500 installed, and it is the right answer for a lot of rental properties, hall bathrooms, and budgets that need to stay tight. The tradeoff is the look and the lifespan. Acrylic surrounds are serviceable, but they read as what they are, and they do not add much at resale.

The middle tier is a tiled shower built in the same footprint. Same alcove, same drain location, but now you are paying for a proper shower pan, waterproofing, tile, a glass door, and the labor to do all of it correctly. That runs $6,500 to $12,000 in Denver, with tile selection and glass driving most of the swing inside that range. This is the tier most homeowners actually want once they see the difference, and it is where the majority of our conversions land.

The top tier is a conversion that moves plumbing or expands the footprint. Maybe you are stealing space from a closet to make the shower wider, or relocating the drain to change the layout, or turning a cramped five-foot alcove into a real walk-in. Once plumbing moves, you are into demolition of the subfloor or the ceiling below, new supply and drain lines, framing changes, and a bigger tile package. Expect $12,000 to $20,000, and if the scope keeps growing, it is worth reading a full breakdown of walk-in shower costs in Denver before you commit, because at that point you are building a walk-in shower, not converting a tub.

What the tub has been hiding

Here is the part no quote can fully predict. A tub that has been sitting in place for forty or sixty years has been covering the wall framing, the supply lines, and a section of subfloor that nobody has laid eyes on since the house was built. In Denver's older housing stock, the neighborhoods full of homes built before 1970, we routinely find galvanized supply lines behind the tub. Galvanized pipe corrodes from the inside, chokes water flow, and eventually leaks, and no experienced contractor will tie a new shower valve into failing galvanized and walk away. Replacing that section of pipe is not optional once it is exposed.

The other common find is subfloor damage. Tubs leak slowly, at the drain gasket or the overflow or the caulk line, and the water goes straight down into the wood. We open up tub alcoves and find soft, blackened subfloor more often than homeowners would guess. Fixing it is not expensive in isolation, usually a few hundred to a couple thousand dollars, but it has to happen before the new pan goes in. This is why we tell every conversion client to carry a contingency of 10 to 15 percent on top of the quoted price. The mistake homeowners make is treating the quote as the ceiling. The quote is the price for the work everyone can see. The contingency covers the work nobody can see until demolition day, and if you do not need it, you keep it.

Permits, and when Denver requires one

If your conversion keeps the drain and valve in the same location and simply swaps fixtures, the permitting picture is light. The moment plumbing changes, and moving a drain or rerouting supply lines counts, Denver requires a plumbing permit and inspection. Some homeowners see the permit as a fee and a delay and ask whether it can be skipped. It should not be. An inspected shower is a documented shower, and unpermitted plumbing work is exactly the kind of thing that surfaces during a home sale inspection and turns into a negotiation against you. Permit costs on a project this size are modest, typically a few hundred dollars, and a contractor who handles permits routinely will fold the timeline into the schedule so it costs you little in calendar time. We pull the permits, schedule the inspections, and coordinate the trades. That is the job.

The resale question nobody asks until later

Before you remove any tub, count the tubs in your house. If the answer after the conversion is zero, stop and think. Families with young children bathe them in tubs, and a house with no tub at all narrows your future buyer pool in a measurable way. Our standing advice in Denver is to keep at least one tub in the house, usually in a hall or kids' bathroom, and convert freely everywhere else. If you are working on your only full bathroom, the decision gets harder, and it is worth working through the tub versus walk-in shower decision in detail before demolition starts, because this is the one part of the project you cannot cheaply undo. Homeowners who convert their only tub and regret it are paying for two remodels where one would have done.

When a conversion becomes a remodel

A conversion has a way of growing. Once the tub is out and the walls are open, the vanity looks tired, the floor tile does not match the new shower, and the lighting is twenty years old. There is nothing wrong with expanding the scope, and doing it all at once is genuinely cheaper than doing it in stages, because the trades are already mobilized and the bathroom is already torn up. But you should expand the scope on purpose, with a budget, not by a series of small yeses that each add a thousand dollars. If you suspect your project is really a bathroom remodel wearing a conversion's clothes, look at what full bathroom remodels cost in Denver and decide up front which project you are doing. The homeowners who get in trouble are the ones who priced a $6,000 conversion and made $14,000 of decisions one at a time.

Getting a number you can trust

A trustworthy conversion quote names the tier, states what happens if galvanized pipe or damaged subfloor shows up, and tells you whether a permit is required for your specific scope. If a quote is silent on all three, it is not a lower price, it is an incomplete one. When you are ready to get real numbers on your bathroom, our team can walk the space, tell you which tier your project actually falls into, and give you a price that accounts for the age of your house. You can see how we approach bathroom remodeling projects across the Denver metro and reach out when it makes sense for you. The conversion itself usually takes one to two weeks. Getting the scope right before demolition is what keeps it there.
