What Is the Weight Limit for an Acrylic Bathtub?

You are either constructing, thinking of constructing, or of doing some kind of remodeling to your bathroom. You investigate materials, colors, and even shapes. But then the critical question arises: what is the weight limit for an acrylic bathtub?

You might have your doubts. After all, an acrylic bathtub weighs way less than a regular porcelain bathtub, so you might think it is more fragile. Well, let’s answer all of your questions regarding the weight limits of acrylic bathtubs before you make any decision.

What Is the Weight Limit for an Acrylic Bathtub?

Acrylic is a light material, but that doesn’t mean it is fragile at all. The smallest acrylic bathtub can hold between 292 pounds, and the biggest up to 1,001 pounds, but how much water — plus human — it can hold is not the only thing you should consider when choosing the right bathtub for your home.

If you want to make sure both your bathtub and your home have a long lifespan, and also that the bathtub you select is the right one for you, take a look at these considerations before you make a choice.

The structure where you are going to place your acrylic bathtub

There are a few things you need to check before you buy and install a new bathtub. If you are remodeling, make sure the subfloor is structurally ok. Especially if it is a bathroom on the second floor.

Type of Acrylic Bathtub

Not every bathtub is the same, nor it has the same purpose. So, let’s take a look at the different types of bathtub you can get on acrylic, and what are their weight limits.

Alcove Bathtub

This is your most common type of bathtub. You can only see one of its sides because the other three are surrounded by walls. This makes it ideal when you want to have a bath-shower combination, too. This type of bathtub, when made of acrylic, can hold a weight of 333 lbs to 667 lbs.

Freestanding Bathtub

These types of bathtubs have very modern designs and are a great choice if you want to add some style to your bathroom, without sacrificing all your budget. But since they are made to stand on their own, without any wall support, you do need to have enough space.

You can find them in full circles, ovals, and even some curvy squares which will give your space a lot of glamour.

Acrylic freestanding bathtubs can hold from 292 lbs to 917 lbs of weight.

Corner Bathtubs

If you want your new bathroom to be a place to relax, then a corner bathtub can be a good choice. They normally have a triangular shape and stand between two walls. They might be relaxing, but they do take up a lot of useful space, so you should have that in mind if you are thinking of buying one.

Acrylic corner bathtubs support between 333 lbs to 1.001 lbs of weight.

Walk-In Bathtubs

This type of bathtub is perfect for people who have some type of mobility issue, because they have a watertight door, letting the person in, without having to lift their legs too high, or use a step. They also have a seat, so the person taking a bath can do it comfortably and safely. Another useful characteristic of these types of bathtubs is that they are designed to drain fast, so the person bathing won’t get cold before they can get out of the bathtub.

Walk-in bathtubs have a weight limit between 333 lbs to 751 lbs.

Drop-in Bathtub

This type of bathtub is similar to alcove bathtubs but instead of having one side finished, there are none. But don’t worry, this doesn’t mean that you will end up with some kind of Terminator skeleton in your bathroom. Drop-in bathtubs are meant to be dropped in an enclosed space, being this in the shape of a tub, finished matching the walls and decorations of your bathrooms, or even a small pool, at the floor level.

Acrylic drop-in bathtubs can hold between 500 lbs and 667 lbs of weight.

If you need a precise number to know the weight limit of the acrylic bathtub you are interested in…

You can calculate how much weight a specific model can hold by knowing how many gallons of water it can hold. With that piece of information, you multiply the number of gallons by 8.34 —which is what a gallon of water weights— and you’ll get to know your acrylic bathtub weight limit. Ot at least the minimum amount of weight it can withstand.
