If you have a bathroom renovation on the horizon, or are even just dreaming of one in the future… there are a few standard measurements you’ll want to save and reference. I’ve been deep in bath design these past few weeks, working on our primary bath plans. From vanity height to shower spacing, nailing down the correct bathroom dimensions can mean the difference between a space that feels awkward… and one that functions like it was professionally designed. Over the years, I’ve tackled a LOT of bathroom remodels (for our homes and for clients)– these are the go-to measurements I reference again and again. Whether you’re working with a compact space or are planning a spacious primary suite, this guide is filled with standard bathroom dimensions to help you create a layout that’s beautiful, efficient, and most importantly- comfortable.
I’m using images from our guest bathroom as examples throughout this post- for easy visuals. It was the very first room we renovated in our current home… over six years ago! I think it’s withstanding the test of time- I still love this space.
Why Bathroom Dimensions Are Important
Bathrooms may be small, but they’re arguably one of the most functional rooms in a home, next to the kitchen. Getting the right spacing ensures everything works together seamlessly- drawers open without hitting the toilet, the vanity doesn’t crowd the shower, and your towel hooks are actually within reach when you need them. It’s thoughtful design that elevates a space from just “done” to truly well planned. However, unless you’re an industry professional… these dimensions aren’t typically common knowledge. Because a lot of time and money goes into renovating, I wanted to compile an easy guide you can pin, save, or bookmark for your next bathroom makeover! I hope this is helpful…
Key Bathroom Dimensions To Save
Door & Entry Clearance
Standard Door Width: 28–32 inches
Swing Clearance: Make sure doors can open fully without hitting fixtures or cabinetry
If you’re tight on space, pocket doors are the ideal alternative- and my personal preference. I would not recommend barn doors, if you’re going for a timeless and functional aesthetic.
Vanity Height
Standard: 32–36 inches
This is a comfortable height for most adults and works well in both primary and guest baths. In kids’ bathrooms, some designers lower it slightly, to around 32″. However, I’d recommend keeping it closer to 34″, for resale. And remember… kids grow!
Designer Insight: I usually opt for ~35″… that seems to be the sweet spot in the majority of our spaces and my personal design preference.
Vanity Depth and Clearance
Standard Vanity Depth: 21 inches
Front Clearance: 28–36 inches (my preference is 30″ minimum)
This ensures there’s enough space to walk around and open cabinet doors or drawers without obstruction.
Double Vanity Spacing
Standard Double Vanity Size: 48–72 inches
Between Sinks: 30 inches center-to-center (standard)
A double vanity is a real luxury, and allows each person their own space… these dimensions help avoid elbow-bumping in the morning rush.
Toilet Placement
Side Clearance: 15 inches minimum (from wall to center of toilet)
Front Clearance: 24–30 inches
If you have the room, more space is always better- especially in primary bathrooms or shared family baths. Having a designated water closet in your floor plan is definitely an added luxury.
Shower Dimensions
Minimum Shower Size: 30” x 30”
Ideal Shower Size: 36” x 48” (or larger)
Bench Height: 17–19 inches (above the finished floor)
Niche or Product Ledge Height: ~42 inches (minimum) above the finished floor
Design Tip: I always include a built-in niche or ledge in showers for function and aesthetic. It’s worth planning in advance! Check out this post on how to plan and design a shower niche.
Bathtub Dimensions
Standard Tub Size: 60” x 30”
Freestanding Tub Clearance: 6″ (minimum) on all sides
Drop-in tubs are great for tight spaces, while freestanding tubs need breathing room to really shine… more space is always better, but six inches is the minimum.
Towel Bar and Hook Heights
Towel Bars: 42–48 inches above the finished floor
Towel Hooks: 60–70 inches above the finished floor
Robe Hooks (behind doors): 60–70 inches above the finished floor
Towel bars and hooks are one dimension you can certainly play around with… take more creative freedom with these dimensions. They’re dependent on your height, reach, the overall space, and are easy to adjust.
Mirror Placement
Distance from Countertop: 5–10 inches above the counter or vanity top
Distance Above Finished Floor: 60–65 inches
This can be adjusted based on the size of the mirror and your lighting layout. The mirror should sit at eye level… not too high or too low.
FAQ
36” x 48” is ideal for comfort. The minimum is 30” x 30”, but if you have the space… go larger and add a bench or ledge!
It depends! Freestanding tubs need at least 6″ of clearance on all sides. If that’s tight, a drop-in tub might work better. That said, in our primary bath I’m designing right now… we’re ordering a freestanding tub and it’s going to be tight (pushing 6″to 8″ of negative space).
This is dependent on your shower and tile size. I often like to stack them, creating a double niche for a better sense of scale… this provides balance for plumbing fixtures, but it’s dependent on your layout and materials.
