Outline the placement of the tub on the floor. Get help from a partner and flip the tub upside down on the floor. Line up the drain with the hole in the tub. Outline the shape of the tub on the floor with chalk. Draw an arrow on the floor to indicate the position of each leg.
Place 2-part epoxy cement on the bottom of the bathtub’s legs. Follow the manufacturer's instructions so you mix the cement properly before applying it to the tub.
Return the tub to its upright position, taking care not to make contact with the epoxy cement. Use the outline you marked on the floor to set the tub in the correct position. Press down on the bathtub firmly so the epoxy cement secures the tub legs to the floor.
Make a watertight seal between the bathtub skirt and the floor by applying a bead of waterproof silicone adhesive between the two. Use a caulk finishing tool along the bead of silicone that you placed between the skirt and the floor to help smooth out the adhesive and give it a finished look.
Hook up the plumbing lines for the drain, overflow assembly and faucets, following the manufacturer’s instructions. Most bathtub and faucet kits come with all the hardware needed to accomplish this task.
Carefully flip the tub upside down and install the feet on the bottom of the tub if they aren't pre-installed. Follow the manufacturer’s instructions regarding the placement of the feet or you may end up with a tub that is not level. If the freestyle tub is too heavy to lift, prop up the end onto a strong, padded box instead.
Put tub feet coasters on the bottom of the bathtub feet. Homeowners generally use the coasters to protect the floor from accidental scratches.
Line up the bathtub’s drain with the appropriate plumbing line in the floor.
Adjust the level of the bathtub using the provided spacers or by adjusting the leveling feet. In some models the adjusting feet are concealed within the tub's support frame. In the event that your tub or floor is not level, the spacers and leveling feet help prevent unnecessary tilting that can damage the plumbing or your floor.
Put the faucet, drain and overflow assembly components together, per the manufacturer’s instructions. Most freestanding tubs come with the necessary components you need to accomplish this task.
