Combo Tub-Shower Cost: What to Expect in 2026

A combo tub-shower typically costs between $3,000 and $10,000 when installed, with the tub unit itself ranging from $1,500 to $6,000 for acrylic models. The final price depends on the material, whether you are replacing an existing tub or converting a space, and what electrical or plumbing work your bathroom requires. This guide breaks down each cost layer so you can compare quotes and plan your budget.

H2: Combo Tub-Shower Unit Prices by Material

The tub unit is the largest single line item in most projects. Acrylic is a common choice for walk-in and combo tubs because it is lightweight and retains heat well. A standard acrylic tub unit generally costs $1,500 to $6,000 before installation. Gelcoat units are usually less expensive, with materials priced around $1,000 to $3,500.

Material choice affects more than the purchase price. Acrylic tends to resist chipping and can be easier to repair over time, while gelcoat is a thinner coating over fiberglass that may show wear sooner. Neither material changes the basic footprint of a standard alcove combo tub-shower, which usually fits in a 60-inch by 30-inch space, though you should measure your rough-in before ordering.

H2: Standard Installed Cost Range

Once labor, old-tub removal, plumbing hookups, and surround installation are included, a standard installed combo tub-shower typically falls between $3,000 and $10,000. That range assumes a straightforward replacement in an existing bathroom where the drain and water supply lines do not need to move.

Here is how the math can look for a mid-range project:

• Acrylic tub unit: $3,500
• Delivery and removal of old tub: $600
• Plumbing connections and surround: $2,400
• Labor for installation: $1,500
• Subtotal: $8,000

If your contractor needs to move the drain or reinforce the floor, labor hours increase and the project can move toward the top of the range. For more on what installation involves, see our overview of walk-in tub installation.

H2: Electrical and Permit Costs

Electrical work and permits are often overlooked in early estimates. If your combo tub-shower includes a heated seat, whirlpool pump, or other powered feature, you may need a dedicated circuit and GFCI protection. Electrical and permit costs typically add $300 to $1,200 to the total.

Permit requirements vary by city and county. Some jurisdictions require a plumbing permit whenever a tub is replaced, while others only require one if you alter the drain or vent stack. Electrical permits are common when new wiring is involved. Failing to pull required permits can create problems when you sell the home, so it is worth asking your contractor which permits apply to your address.

H2: Door Seal and Long-Term Maintenance

If you are considering a walk-in combo tub-shower, the door seal is a part you will eventually need to replace. Door seal replacement usually costs $150 to $500, depending on the tub model and whether a service technician performs the work. A leaking seal can damage the subfloor, so addressing it promptly is cheaper than repairing water damage later.

Routine maintenance also protects your investment. Wiping down the tub and shower surround after use reduces soap scum and mildew buildup. Checking the door latch and seal every few months helps you catch wear before it becomes a leak. For a full maintenance checklist, see our guide to walk-in tub maintenance.

H2: Combo Tub-Shower vs. Walk-In Shower Conversion

Some homeowners weigh a combo tub-shower against removing the tub entirely for a walk-in shower. A walk-in shower conversion typically costs $3,000 to $12,000, which is often higher than a standard combo tub-shower installation because it involves waterproofing a larger floor area, installing a curbless or low-threshold base, and sometimes moving the drain.

A combo tub-shower keeps both functions in one footprint, which can be practical for households with children or for resale value in markets where buyers expect at least one tub. A walk-in shower may be easier to step into, but it removes the soaking option entirely. For a direct comparison, see our article on walk-in tub vs. walk-in shower.

H2: Hidden Costs and Budget Buffers

Beyond the unit and installation, several costs can push a project beyond the initial quote. Floor repair is common if the old tub leaked and damaged the subfloor. Replacing rotted plywood or joists can add several hundred dollars. Wall repairs around the old tub surround may also be necessary once the old unit is removed.

If you are upgrading from a standard tub to a deeper soaking combo unit, you should confirm that your water heater can fill it without running out of hot water. A larger tub may require a larger water heater or a tempering valve, which adds to the plumbing cost. Electrical upgrades, as noted above, can add $300 to $1,200.

It is wise to set aside a contingency of 10 to 20 percent of the total project cost. On a $7,000 installation, that means keeping $700 to $1,400 available for surprises. This is an estimate, not a guarantee, and actual costs vary by contractor and region.

H2: Getting an Accurate Quote

To compare quotes fairly, ask each contractor for an itemized estimate that lists the tub unit, delivery, old-tub removal, plumbing, surround, labor, permits, and electrical work separately. This makes it easier to spot where one quote is higher and why.

Measure your bathroom before you shop. Record the width, depth, and height of the alcove, the location of the drain, and the distance to the water supply. A tub that does not fit your rough-in will cost more to adapt than one that matches your existing layout. If you are doing some of the work yourself, our DIY walk-in tub article covers what homeowners can reasonably handle and where professional help is usually worth the cost.

If your existing tub is structurally sound but the finish is worn, refinishing may cost less than full replacement. However, refinishing does not address a leaking door seal or outdated plumbing, so it is not always the better long-term value. For repair-specific costs, see our walk-in tub repair guide.

H2: Bottom Line

A combo tub-shower unit costs $1,500 to $6,000 for acrylic materials, while gelcoat units run $1,000 to $3,500. Standard installed projects typically land between $3,000 and $10,000, with electrical and permits adding $300 to $1,200. Door seal replacement, when needed later, usually costs $150 to $500. Measure your space, confirm permit requirements, and request itemized quotes before signing a contract.
