Do you miss soaking in a hot soak in the bath after a long day of driving and exploring? You may be surprised to learn that RV bathtubs are not the same as standard bathtubs used in houses. Usually, when you think of a bathtub the image of a large heavy white tub comes to mind, right? So how does that work in the confined and weight-conscious space within an RV?

Let’s dive in and see how you can add a little luxury to your life on wheels by installing one of these RV bathtubs. 

How Is an RV Bathtub Different from a Normal Bathtub?

You may think any bathtub can work as long as it fits, right? Unfortunately, this isn’t the case. You need a bathtub specifically designed for RVs. These utilize lighter materials, which decreases any unnecessary weight. RV bathtubs often employ sturdy plastic, which is much lighter than porcelain while still holding up well. 

Can You Add a Bathtub to Any RV?

If you want to replace a shower with a bathtub in your RV, make sure it fits. It’s just like bathroom renovations in a home. The bathtub will be smaller than you might be used to because it has to fit in a tighter space. However, it should still fit an average-sized adult. Some argue for showers only in order to conserve water, but it all comes down to how you want to ration your water.

How to Install an RV Bathtub

Installing a new tub may seem like a daunting task, but don’t get overwhelmed. All it takes is 10 simple steps. And while some steps may take longer than others, this list will keep you on track.

Gather Your Tools

Bring out the tools! Measure everything carefully before getting started, so you know if your new tub will fit. Get your new fixtures and plumbing ready to go, as well as any adhesive you may be using. You’ll also need a screwdriver for the surround and fixtures and possibly a drill to cut the hole in the new tub for the drain. The better prepared you are, the less chaotic this renovation will be. 

1. Remove the Shower Bar/External Accessories

The shower bar should be very firmly attached to the wall with adhesive, so it might take some extra strength to get it out. Once you get that off, you can fold up the curtain if you plan on reusing it. You could also just plan on replacing everything for a whole new look.

2. Shut Off Water and Remove Fixtures

Knowing where your water supply is in your RV is helpful whether you’re renovating or not. Removing the RV bathtub won’t be safe until you turn off the water. Otherwise, you could cause flooding. You can also remove any other fixtures you might have that could get in the way. 

3. Rip Out the Tub Surround and Retainer Strip

You probably can’t replace the tub without cracking and damaging the surround and retainer strip, so it’s better just to plan on replacing those as well. Take a sharp knife or box cutter and trace along the caulk. It should fall right out. It’ll be messy, but it’ll look great once it’s finished. 

4. Remove the Drain

One easy way to remove a drain is to insert a pair of pliers, then grip those pliers with a wrench. When you turn the wrench, the pressure from the pliers will pop the drain right out. However, if that doesn’t work, you might need to go straight to the source and remove it from beneath. 

5. Remove the Tub

Once you get the old drain out of the tub and unscrew the plumbing, the tub should come right out. Just pull and lift. As long as it’s not still attached to the surround or the drain, nothing is holding it in place. 

6. Attach Drain to New Tub

It’s important to do this step correctly. Otherwise, you could flood the bathroom once you turn the water back on. You can actually insert the new drain and tighten the plumbing before you even install the new tub. Make sure it’s nice and tight, so you don’t have any leaks. 

7. Install New Tub

Set the new RV bathtub in place and make sure it fits properly. Even when you measure everything properly, sometimes things just don’t fit the way you expect. Once you settle the tub in, finish attaching the plumbing. It should hold the tub in place without shifting around. 

8. Install Enclosure

Place your new surround against the wall with a fresh retainer strip. The surround should be pretty lightweight, so be careful you place it correctly, and it doesn’t shift around. You can use adhesive tape, gorilla glue, and screws to help keep it secure. 

9. Replace All Plumbing and Fixtures

If you’re replacing the tub, it’s likely the faucet also needs an update. And you might as well get a showerhead if this tub is doubling up as a shower. It’s nice to have the same material for all the fixtures in the bathroom, so everything matches and looks put together. 

10. Replace Seal

Add some caulk along the tub’s edges to keep it extra secure and protect the bathroom from water damage. This will take a steady hand and some drying time, especially in a wet environment. Once it’s all dry and cleaned, turn the water back on and enjoy your new bathroom. 

Sometimes you just really need a nice hot bath at the end of the day, especially if you’ve been hiking and exploring. Camping and comfort may not always go hand in hand, but having a bathtub in your RV (even a small one) can make your home on wheels cozier. If you’re up for a new DIY project and want to make some upgrades to your bathroom, a new tub is a great choice. Have you ever replaced your RV bathtub?
