Guide
Choosing a CleanCut product comes down to a few measurements of your bathtub and one question: do you still want to take baths? This CleanCut sizing guide explains how to measure, what each model needs, how the sizes differ, and what to do if your numbers land close to a limit.
There are four CleanCut products. Each one lowers part of the tub wall to create an easier step-in entry, and each one keeps the bathtub you already have. Working out which CleanCut product suits you starts here.
All four come in White or Beige. The chart below puts the key figures side by side.
For many standard bathtubs.
For medium-height soaker tubs that need more height taken off than the Step.
For taller, high-profile tubs. The lowest step-in CleanCut option.
A lower step-in opening with a removable watertight insert, so you can still take a bath.
You need a tape measure and a few minutes. Take each measurement on the section of tub wall you step over. If you would like to see it done first, watch the tub measuring and installation videos.
Measure across the top of the tub wall, from the inside edge to the outside edge. Use the widest point along the section you step over.
Each CleanCut product has its own measuring depth. Measure down the inside of the tub wall to that depth, then measure the width of the wall at that point. For the Step, that is 9.75 in. down on the inside. The table in the next section lists the depth for every model.
Tub height helps decide which model makes sense and how low the new entry will end up. It matters most for the CleanCut Ultra-Low: the tub must be at least 14.75 in. tall, inside and outside.
Write all three numbers down before you compare them with the requirements.
These are the core limits from the CleanCut sizing guide. Your tub wall must be no wider than the maximum at the top, and no wider than the maximum at the measuring depth.
| Model and size | Max width at top | Measuring depth (inside) | Max width at that depth |
|---|---|---|---|
| Step, Small | 4 in. | 9.75 in. | 4.75 in. |
| Step, Medium | 4.5 in. | 9.75 in. | 5.75 in. |
| Step, Large | 6 in. | 9.75 in. | 7.25 in. |
| Deep Step, Large | 6 in. | 11.75 in. | 7.25 in. |
| Deep Step, Extra-Large | 8 in. | 11.75 in. | 9 in. |
| Ultra-Low | 6 in. | 14.75 in. | 7.25 in. |
| Convertible | 6 in. | 10.5 in. | 7 in. |
The sizing guide is plain about this: if your tub exceeds the maximum measurements, the product will not work with your tub.
The CleanCut Step is the starting point for many standard tubs. Your two width measurements decide the size, from the Small for narrower walls to the Large for wider ones. Kit numbers are 798601-03 in White and 801701-03 in Beige.
The CleanCut Deep Step is measured at 11.75 in. down, lower than the Step, and its cutting template is taller. Choose the Large or the Extra-Large based on your widths. Kit numbers are 823001-02 in White and 826001-02 in Beige.
The CleanCut Ultra-Low comes in one size. It needs a tub at least 14.75 in. tall inside and outside, a top width of no more than 6 in., and a width of no more than 7.25 in. at 14.75 in. down. Kit numbers are 804801 in White and 804802 in Beige.
The CleanCut Convertible also comes in one size. It is measured at 10.5 in. down, with a maximum of 6 in. at the top and 7 in. at the measuring depth. Its watertight centre insert weighs about 2 lb: take it out for step-in showering and put it back to fill the tub for a bath. It must be properly installed. Kit numbers are 807901 in White and 807902 in Beige.
Sizes exist to fit tub walls of different widths. The cutting template is the same for every Step size, and the same for both Deep Step sizes.
The finished opening is the same on all three Step sizes: 24 in. wide and 8.5 in. from top to bottom. Only the wall widths each size fits are different.
Both of your measurements need to fit within the limits of the size you choose. If they fit more than one size, or sit right at a boundary, ask before ordering.
A few figures in the comparison chart describe the experience of using the tub rather than the fit.
The cardboard cutting template is 25.5 in. long on every model. Its height is what changes: 8.5 in. for the Step and Convertible, 11 in. for the Deep Step and 14 in. for the Ultra-Low. A taller template means a deeper cut and a lower entry.
The approximate height removed from the tub wall is the figure that matters most to the person stepping in. Your new step-over is roughly your tub's height less that amount, so a taller tub still leaves a taller step after the cutout.
Height removed and template height are two different measurements, so they are never the same number:
| Product | Approximate height removed from the tub wall | Cutting template height |
|---|---|---|
| CleanCut Step | About 8 in. | 8.5 in. |
| CleanCut Deep Step | About 10.5 in. | 11 in. |
| CleanCut Ultra-Low | About 13.25 in. | 14 in. |
| CleanCut Convertible | About 8 in. | 8.5 in. |
The template marks where to cut; the height removed is how much lower the finished entry is once the insert is fitted.
The opening width is the room you have to place a foot as you step through. The Step, Deep Step and Ultra-Low all open to 24 in. at the top, narrowing to between 20 and 20.75 in. at the bottom. The Convertible is narrower, at 18.75 in. at the top and 15.5 in. at the bottom. If extra room matters in your household, weigh that against keeping the option of a full bath.
For something to hold while stepping in and out, the 16.5 in. clamp-on Molded Tub Bar can be added to any of them.
Measurements close to a maximum are where sizing mistakes happen. Before you order:
Is your tub cast iron, or would you prefer someone experienced to confirm the fit? Imperial Bathrooms can connect you with an independent installer experienced with CleanCut products. Their quote can cover the product and the installation, so you don't need to buy a kit first. Start with an installation quote request and expect a response within 2 business hours.

Measure the width of the tub wall across the top rail, then measure the wall width again at the depth listed for each product (for example, 9.75 inches down on the inside for the Step). Compare both numbers with the sizing guide. If your measurements are close to a limit or your tub has an unusual shape, ask before ordering.
It depends on your tub's height, the width of the tub wall at the top rail and lower down, and whether you want to keep full-bath use. The Step suits many standard tubs, the Deep Step suits medium-height soaker tubs, the Ultra-Low is for taller high-profile tubs, and the Convertible keeps the option of a bath. An installer can confirm the fit, or you can compare your measurements with the sizing guide.
Approximately how much is removed from the tub wall: about 8 inches with the Step and the Convertible, about 10.5 inches with the Deep Step, and about 13.25 inches with the Ultra-Low. Your final step-over height depends on how tall your tub is to begin with.
With the CleanCut Convertible, yes. It has a removable watertight insert: take it out for an easier step-in shower, and put it back in when you want to fill the tub for a bath. The Step, Deep Step and Ultra-Low create a permanent step-in opening.
Clawfoot tubs can't be modified because they don't have a conventional wall running down to the floor. Jetted tubs aren't recommended, because water lines may run inside the tub wall. A tub with an existing liner can often be modified with a Double Cut, cutting through the liner and then the original tub. Garden-style tubs vary widely, so they need a review of photos and measurements before anything is ordered.
