Cutting the tub
There are four basic types of tubs. It is recommended that you wear suitable eye, ear, face and respiratory protection when cutting them. I will address these tubs in 3 separate categories. On all types of tubs, I suggest cutting the inside wall of the tub first, then the outside wall of the tub, then the top rail of the tub.
Checking the cut
Mounting the 4 metal angle brackets
These mount on the inside of the bottom horizontal walls, 2 on the inside wall, and 2 on the outside wall. It isn't critical exactly where these are mounted on the walls, but try to stay fairly close to the left and right ends. Use LOCKTITE TUB AND SHOWER SURROUND ADHESIVE and mount with the bracket facing in and flush with cut.
Assembling the conversion kit
Assemble the left vertical plate to the base plate with the screws provided. You should still be able to see the mark, "left" on the vertical plate after attaching it to the base plate. Repeat this procedure with the right plate.

3. Measure the Top Thickness of the Tub - See FIGURE 3
A. Measure the thickness of the wall, at the top, below the inside and outside rounded edges.

2. Measure the Length of the Cut - See FIGURE 2
A. Determine the location of objects which may interfere with the use of a saw while cutting, such as the toilet or cabinetry.
B. The opening may be in the center or offset to either side of the tub. If you would like to offset the opening, stay at least 12" away from the end of the tub.
C. Make a start mark on the top edge of the tub. Measure along the top edge of the tub to the length you want the opening, then place a finish mark.

Tools Needed to Measure Your Tub
Our Kits are Proudly Made in the USA
1. Measure the Depth of the Cut - See FIGURE 1
A. Place a straight edge across the top of the tub.
B. Measure from the bottom center of the tub to the bottom of the straight edge.
C. Deduct 3" from that measurement (Ex: 12" tub depth - 3" = 9" deep cut).

4. Measure the Bottom Thickness of the Tub - See FIGURE 4
A. On the inside of the tub wall, in line with the start and finish marks, measure down the depth of the cut.
B. Place one end of a level on this mark, level up vertically, and measure from the level to the outside edge of tub.
If you have a standard tub with no Offset and your tub is not Curved, you are finished taking measurements! Please fill out the form and submit so that we can begin building your custom kit right away!
If your tub has an Offset on the outer wall or the outer wall is Curved,

6. Measuring a Curved Tub (if Applicable) - See FIGURE 6
A. Take Depth, Width, Bottom, and Top measurements as outlined in Steps 1 - 4 above.
B. Set straight edge on top of tub at 90 degrees to left cut line and right cut line.
C. Measure distance from wall of the tub to inside edge of the straight edge.
5. Measure the Offset (if Applicable) - See FIGURE 5
A. An offset is a raised, decorative pattern on the outer wall of the tub. If the offset is running horizontally along the tub wall, it will cross the vertical cut lines.
B. Measure from the top of the tub, down to the center of the offset.
C. Then measure how far the offset protrudes from the outer wall of the tub.
D. Make a note of the Offset measurements with reference to the Illustration it matches.
