However, if you follow the steps mentioned in the article properly, you should be able to install your bathtub without access underneath in no time.

So, let’s not waste any more time and get started, shall we?

Step 1: Cutting A Hole In The Drywall

When you need to install a bathtub and have no access underneath, the first step is to create a hole in the drywall. It may sound complicated. But it is actually quite an easy thing to do. Though there are several things you should take care of:

  • Ensure you got the right tools. Search your supplies and take out a saw, some drywall screws, and of course, a drill.
  • Make precise measurements for the hole. Make sure that the hole is not too large or too small in size.
  • Be careful of your surroundings. You don’t want to damage the rest of the drywall while making your cut.

Step 2: Installing The Brackets

Using the brackets becomes very important when you are trying to install a bathtub and have no access underneath. The brackets are necessary to secure the bathtub in place. You can get brackets at almost any hardware store. Just follow the manufacturers’ instructions and you will be able to install them without facing any trouble.

Step 3: Setting The Bathtub In Place

Setting A bathtub sounds simple enough. But when installing a tub with no access underneath, you will have to follow a few additional steps. They are necessary to ensure that everything is set in the right place properly.

Start by setting the bathtub in the right location. Outline the spots in which the tub’s feet will sit on the floor. After marking, you can take away the tub. Now you need to drill the marked spots on the floor to make holes. 

Once you are done making holes, it is time to set the bathtub in its right place. To do this properly, you need to insert the shims inside the holes. Then just gently set the bathtub into its proper place. You can use the level tool to ensure that the bathtub is set evenly. 

Step 4: Securing The Bathtub

Once you are done with setting the tub evenly in its proper place, you should secure the bathtub in its place using screws. In the previous step, you made some holes in the floor using the drill. 

In this step, the screws should go into those previously drilled holes. Insert the screws properly. Make use of the nuts and washers to secure them in their appropriate places. 

Step 5: Testing For Leaks

Once you are done with all these settings and securing, you might be thinking that your job here is done. Well, not yet. Before starting on the finishing touches, it is wise to make sure that the tub is set properly and isn’t leaking from anywhere.

To check for leaks, you should wait for a few hours. Then fill in the tub with water and check carefully for any leaks. If there is a leak, you will probably be able to hear a faint dripping sound. If that’s the case, find out where the leak is and repair it. If there is no leak, you are all ready for the next step.

Step 6: Patching The Hole In The Drywall

If everything is in order, it is now time to patch up the holes you created in your drywall to install your bathtub. The bathtub’s front edge should be caulked where it touches the ground. After the hole is all patched up, repaint it properly. And your work here is done. 

Frequently Asked Questions
