Hi there, intrepid DIY'er! By now, you know your way around the toolbox, you’ve powered through enough painting jobs to give Michelangelo a run for his money, and your tile setting game is on point. Now, you're ready for another home improvement challenge: installing a new bathtub. But hang on just a minute, tub-thumper. Before you set foot in the hardware store, you need to ask yourself a crucial question: Just how much space do you need to install that new bathtub?

Hold Your Soapy Horses, How Do You Choose a Bathtub Size?

How big or small your bathtub should be depends on several factors. Such as:

The size of your existing bathroom

Pull out that measuring tape and make a note of dimensions. Typically, the length ranges between five and six feet, and the width from 30 to 36 inches. There are smaller tubs too, at about 48 inches long, if your room is more compact.

The size of the existing bathtub (if any)

If you're replacing an old bathtub, you might want to stick to the current tub's size, especially if you aren't planning on remodeling your whole bathroom. Bathing in your budget, remember?

Your family’s bathing needs

Consider who will be using the tub. Do you need a deep soaker tub for your end-of-the-day relaxation, a standard-sized tub for the kids, or a bathtub large enough for two if you enjoy romantic bubble baths with your partner?

The Tub's Footprint

Great! You've decided on the size of the bathtub. Now, let's look at the space you'll need to actually install it. Remember: bathtubs aren't just about length and width; don't forget about the third dimension - depth!

In most cases, you need to accommodate a little extra room – typically a few inches after adding the tub rim, apron, or any tiling you're planning.

Access Recommended

Ideally, you should leave at least 30 inches of open space in front of your bathtub to accommodate movement and ease of cleaning. Remember the shower curtain or the glass door, if your tub doubles as a shower, needs its swing space, too. Plus, that rug needs to go somewhere, right?

Plumbing Positioning

Prepare to avoid bobbing for apples in the plumbing world. Consider the positioning of your existing plumbing fixtures. It would definitely spoil the fun (and possibly your budget) if you need to do major re-plumbing to fit your new bathtub.

The Grand Total: Working Out What You Need

Alrighty! So, you've covered the basics and have a rough idea of the space your new bathtub requires. Now, time to use those good ol' math skills to piece everything together. Let's make up an example:

You've chosen a standard 60-inch long, 32-inch wide tub. You add a couple of inches all round for the apron, making it 62x34 inches. If you've space for 30 inches in front, that takes your total bathroom space requirement to 62×64 inches. Does your bathroom measure up?

But Wait! What About Those Multi-Dimensional Tubs?

We talked about length, width, even some access space for relaxing bath times. But what happens when your bathtub isn't your standard rectangular? Think oval tubs, corner tubs, or the luxurious freestanding tubs.

In these cases, you need to take into account the largest length and width for the footprint. And remember, thoughtfulness towards access space is a virtue. You sure don't want to squeeze past a toilet just to be able to enjoy your bubble bath, right?

So, Do You Have The Space To Bathe In Glory?

Installing a new bathtub can refresh your whole bathroom's appeal (and up your DIY cred). But it's a plunge you should take only after thoroughly measuring, calculating and planning. If it all sounds a bit heavy on the math and logistics, remember - the payoff is a hot bath in that tub, surrounded by your handy work, and beaming with DIY pride.

So, DIY'er, I do believe you're equipped to determine the space you need for your new bathtub. Get out there and face down your tub-space-challenge! (And don't forget to update us on your progress!)
