There is no single size that fits every bathroom: compare the product’s outside dimensions and drain position with your finished plans before buying. For example, Salo Manufacturing lists a TS6030 that measures 60 inches wide, 30 inches deep and 73 inches high; that is one model, not a universal standard.
What to check before choosing a one-piece tub-shower combo
Start with the bathroom and installation constraints, then compare products against them. A listing’s nominal width is not enough to establish fit.
- Outside dimensions: Check width, depth and total height against the finished alcove, ceiling and any fixtures or trim that could interfere.
- Drain location: Match left-, right- or center-drain configuration to the existing or planned waste plumbing.
- Delivery path: Account for the unit’s rigid, one-piece construction and the route through doors and hallways into the bathroom.
- Included components: Verify whether the listing includes a drain and overflow, faucet, shower door and other parts needed for the installation.
- Documented features: Compare any stated shelves, floor-surface claims, finish and warranty terms using the specific model’s listing.
- Availability and documentation: Confirm that the exact model and its installation drawing are available for your region and purchase date.
One-piece models and a related alternative
These examples show why dimensions, drain hand and package contents should be checked model by model. They are not a tested ranking, and the available product information does not establish a best-in-class winner.
| Product | Documented details | What to verify |
|---|---|---|
| Salo Manufacturing TS6030 | One-piece tub-shower; 60 inches wide, 30 inches deep and 73 inches high, according to Salo’s product-category listing accessed in 2026. | Confirm the current technical sheet, drain configuration and included components for the exact model. |
| Aquarius G 6092 TS | One-piece tub-shower measuring 60 by 32 inches; the product title specifies a right-hand drain. | Check the full drawing, total height, package contents and whether the right-hand drain suits your plumbing. |
| MAAX Camelia TS-6032 AFR | One-piece acrylic alcove tub-shower; the linked listing is a right-hand-drain configuration. MAAX describes left- and right-hand configurations. | Choose the configuration that matches the rough plumbing and verify the dimensions on its model-specific drawing. |
| Diamond T 603073 | Listed as a one-piece tub/shower. The listing says faucets, drains and doors are not included. | Determine which additional components your installation requires and include them when comparing project cost. |
| Kingston Brass Tulare 60-inch tub combo | Listed as a 60-by-36-inch, three-wall alcove acrylic tub with a sliding shower door and integral tile flange; it is not described as a one-piece unit. | Compare it only if a multi-part tub-and-door setup is acceptable; do not treat it as equivalent to a one-piece assembly. |
How to confirm the unit will fit the alcove
Use the selected model’s installation drawing, not a general 60-inch measurement, to lay out the rough opening. Aquatic’s installation instructions advise checking the manufacturer’s rough-in dimensions against the actual job and making sure the framed alcove is the proper size, square and plumb, with a level floor.

- Slightly narrower for tighter spaces
- Designed with an 18" apron
- Made from solid Vikrell material for strength, durability and lasting beauty
- Modular design allows it to be moved around corners and through doorways with ease
- Curve wall with a smooth, contemporary look, featuring integrated storage shelves
- Measure the finished space and rough opening. Compare the alcove width, depth and height with the exact product drawing. Allow for the surfaces and framing required by the manufacturer’s installation method.
- Check the floor and walls. Verify floor level and that the alcove is square and plumb before setting the unit; correct discrepancies according to the installation plan.
- Plot the drain and plumbing. Match the unit’s drain hand and exact waste-and-overflow location to the plumbing. Aquatic’s guide for its tub-shower instructions calls for a 6-by-12-inch floor opening for the drain, waste and overflow kit; that dimension is specific to those instructions, not a universal opening size.
- Plan the route into the bathroom. Measure doorways and the path from delivery point to alcove. Aquatic warns that the one-piece unit must be brought into the bathroom before door framing is complete, or studs may need to be omitted or removed to allow placement.
- Follow the model’s instructions and local requirements. Use the chosen manufacturer’s installation document for exact dimensions and procedures, and follow applicable plumbing and building requirements.
How to compare the full project, not just the tub
A product price or headline dimension does not describe the complete installation. Make a list of what the selected package supplies and what the job still needs. For instance, Diamond states that faucets, drains and doors are not included with its T 603073. Other products may have different package contents, so confirm them directly rather than assuming that a component shown in marketing material is included.
Also consider whether the assembly can reach the room without altering framing, whether the drain lines up with the plumbing, and whether the product documentation covers the intended installation. A related alcove tub with a separate door may fit a different project, but it is a different construction and should not be presented as a one-piece combo.

Bottom line: choose by drawing and rough-in, not by nominal size
A 60-inch-wide one-piece tub-shower is available, but width alone does not establish compatibility. Select the exact model only after confirming its full dimensions, drain configuration, delivery path and included parts against the bathroom and plumbing plan.
