You probably have a bathtub in your house that is not ideal for relaxing or getting in and out of. Whether a small tub or something larger, it is possible to make an existing tub deeper on a budget. 

This article explains how you can do that and get the look you want with the space you have. 

Types Of Baths

Before we get into details, here’s a quick refresher on the types of baths: 

  • Fixed: 

These baths don’t have removable parts, making them more difficult to install. They also tend to be pricier than other types of baths. 

  • Walk-in: 

These are bathrooms with doors that open up from the inside so people can walk right through them to access the tub instead of entering another room

  • Tiled: 

These are baths with tile on the wall instead of sheetrock, making them look cleaner and newer than sheetrock-only baths.

Use Caulk Strip

If your bathtub is already deep, you might wonder how to make it deeper. DIY-ers can use cardboard and caulk strip to fill the tub with water

Caulk strips are a very easy option and will efficiently create your leak seal. The caulk strip will help you make a watertight seal, and it’s simple to remove compared to alternatives such as moldable glue.

As an alternative to permanently attaching your overflow drain, bind it using adhesive or caulk strip.

The overflow plate has a slider that can be adjusted to fit any tub. It’s made from polypropylene plastic so that it won’t corrode, rust, or tarnish.

This allows you to use the same overflow plate on your bathtub for years!

Make DIY Overflow Plates Using Household Item

You can make your overflow plates with some craft supplies and just a few simple household items.

  • All you need to do is cut out the shape of the plate using cardboard or thin cardboard and then use a pencil to trace it onto some tin foil.
  • Next, remove one side of the tin foil and repeat with another piece so that you have two identical pieces, then cut them out with scissors.
  • Once you’ve finished cutting out the shapes, take two small pieces of duct tape and attach one to each side of the plate. 
  • Next, use a lighter to burn away any excess tin foil on both sides of the plates that won’t be attached to anything so that it will stick securely to your tub shower walls. 
  • Lastly, attach your overflow plates by sticking one into each corner at an angle so they won’t slip while you fill up your bathtub. 

These DIY overflow plates are easy to make but can help save you tons of money when it comes time to replace an updated bathtub! 

Install Porcelain or chrome plates.

Permanently install Porcelain or chrome plates over the overflow drain.

  • One possible solution is to establish a porcelain or chrome plate over the overflow drain, reducing the amount of water that flows into the overflow. 
  • The downside is that you’ll have to replace your overflow plated with a new one, which can be expensive. 
  • The other option is to use a matching cement board and tile adhesive. You could also use silicone caulk as an alternative. 
  • When using silicone caulk, it’s important to ensure it’s not used on any surface other than silicone because it can’t stand up to high heat and may not be meant for exterior applications. 
  • If you’re looking for something more permanent, install a cap over your overflow drain so that no water enters the tub.

Here’s If All Fails!

If All Else Fails, It’s Time For A New Tub.

The most expensive and time-consuming option is to replace the tub with a newly purchased, deep bathtub. 

The next best option is to install a new drain tile in your current tub. This option does require some DIY skills and planning, but you can do it for less than $100. If this is not an option, you can still have the deepest soaking bathtub by installing a new, deeper vanity top. 

To create a deeper soaking bathtub, start by taking measurements of your existing tub. Measure from the floor to the bottom of your existing tub, and then measure from the ground up to where you want to put the new water level. 

Once you have those two measurements, use them for how long you need the new tub’s vanity top. It should be slightly longer than your existing vanity top so that when installed, it will cover up any gaps between the bottom of your existing tub and floor. 

You’ll also need to figure out how wide your new vanity top needs to be because this will determine how deep your new bathtub will be at its widest point.

Advantages of an Immersive Bath Experience

Indulging in a deep soak has manifold benefits, especially with a bathtub depth extender. 

Firstly, it promotes relaxation by allowing the body to fully immerse in warm water, easing muscle tension and stress accumulated throughout the day. 

A deeper soak also enhances the therapeutic effects of hydrotherapy, aiding in the relief of joint pain and improving circulation. 

Additionally, the increased depth provides a more immersive experience, fostering a sense of tranquility and mindfulness, perfect for unwinding after a hectic day or as part of a self-care routine. 

Moreover, a deeper bathtub accommodates individuals of various heights, ensuring everyone can enjoy a luxurious bathing experience tailored to their comfort. 

Ultimately, the benefits of a deep soak extend beyond physical relaxation, offering a rejuvenating escape that nurtures both body and mind.
