How to Measure a Bathroom: 7 Steps Guide

Measuring your bathroom can seem like a big job but it’s an important first step when planning a remodel or new fixtures. Knowing your bathroom dimensions and layout is key to avoiding costly mistakes and everything fitting together from your new bathtub to your new vanity. Before bathroom installation starts, follow these simple steps to measure your bathroom quickly and easily.

Step 1: Get Your Tools

• Measuring tape (preferably one that measures in both inches and centimeters)

• Notepad and pen (or a digital device)

• Graph paper (optional, but useful for drawing the layout)

• Calculator (for any tricky measurements)

Step 2: Measure the Floor Area of the Bathroom

Start by measuring the total floor area of your bathroom. When planning your bathroom remodel consider the average bath size and various bath sizes to make sure the space is functional and looks good. Here’s how:

1. Measure the length and width of the room: Place the measuring tape along one wall to measure the length, then do the same for the width.

2. Calculate the square footage: Multiply the length by the width to get the total square footage of the bathroom. If the room isn’t a perfect rectangle break it down into smaller rectangles and add them up.

For example, if your bathroom is 10 x 8 the total square footage is 80 square feet.

Step 3: Measure the Ceiling Height for Bathroom Measurements

Your ceiling height is important if you’re going to be installing tall units or new lighting. Use your tape measure to measure the distance from the floor to the ceiling at several points around the room to ensure it’s consistent.

Step 4: Measure Doors, Windows and Other Openings

Make sure to account for where doors, windows and any other openings will go:

1. Measure the width and height of each door and window.

2. Measure from the corners to the edge of each door or window. This will ensure any new fixtures won’t obstruct these openings.

Step 5: Measure Fixtures and Features

If you’re keeping existing fixtures like a bath, toilet or sink you’ll need to measure them too:

• Bath: Measure its length, width and height.

• Corner bath: Consider its dimensions, ease of installation and features like built-in seats and jets. Ideal for space saving and unusual bathroom layouts.

• Double ended bath: Note its ability to fit two people, with taps in the middle and sloping ends for a luxurious bathing experience.

• Sink and vanity: Measure its dimensions and note any protrusions.

• Toilet: Measure the distance from the wall behind the toilet to the centre of the waste pipe (known as the “rough-in measurement”).

Step 6: Draw a Rough Layout of the Bathroom

Now you have all your measurements, it’s time to draw a rough layout of your bathroom. Look at different half bathroom layouts and full bathroom layouts to see what works best for your space. You don’t have to be an artist just mark the position of each fixture, door and window and their measurements. Use graph paper to help you keep to scale.

Step 7: Check Your Measurements

Finally check all your measurements to ensure they’re accurate. It’s always good to measure twice and cut once especially when making big decisions about bathroom fittings.

Why Accurate Measurements Matter in Bathroom Design

Accurate bathroom measurements in bathroom design will help you avoid:

• Fixtures that don’t fit: Imagine ordering a new vanity or bath only to find it won’t fit through the door or clashes with other features.

• Wasted materials: With the right measurements you’ll know exactly how much tile, paint or other materials you’ll need, saving you time and money.

• Knowing standard bathtub dimensions and standard UK bath size means you can choose fixtures that fit perfectly, no adjustments needed.

• Better design: You’ll be able to make the most of your space by positioning fixtures in a way that looks and works better.

Conclusion

Measuring your bathroom correctly will save you a lot of trouble later. Follow these steps and you’ll be ready to plan your renovation or refit. Whether you’re working with a designer or doing a DIY bathroom makeover, measurements matter.
