Understanding Shower Sizes That Work
Shower sizes can vary depending on the style, purpose, and layout of your bathroom. If your existing shower is a standard size and youโre planning a bathroom remodel, you might want to keep those dimensions.
Let me explain why this can be a smart choice.
When planning a bathroom remodel, the shower is usually one of the first things people think aboutโand for good reason. A great shower can completely transform how you start or end your day. But before picking out tiles or choosing between a rainhead or handheld shower, youโve got to know your shower sizes.
Understanding the dimensions youโre working with (or planning for) helps everything run more smoothlyโless stress, fewer design hiccups, and often, shorter lead times on materials and installation. Letโs walk you through the basics, and not-so-basics, of standard shower sizes and more.
Standard Shower Dimensions and Sizing Tips for a Smarter Remodel
Standard shower sizes are typically 30 inches by 60 inches or 32 inches by 60 inches in guest bathrooms, and 36 inches by 48 inches or 48 inches by 48 inches in master bathrooms. These dimensions are the most common in the United States, particularly in the Washington D.C. metro area.
If youโre planning a quick refresh and are budget-consciousโperhaps because youโre preparing to sell your home soonโsticking with the existing sizes can save you money. By keeping the plumbing and drain in their current location, you avoid the added expense of relocating them. Additionally, standard shower door sizes are readily available for these dimensions, which means you wonโt need to spend extra on a custom shower enclosure.
Standard Shower Dimensions
Whether youโre remodeling a guest bath or building your dream en suite, knowing the standard shower sizes gives you a solid place to start. Showers come in a range of sizes, from compact setups perfect for tight spaces to luxurious oversized designs with room to spare.
Hereโs a quick breakdown of standard shower sizes:
| Shower Type | Common Dimensions (in inches) |
|---|---|
| Small Showers | 32โณ x 30โณ, 32โณ x 36โณ, 30โณ x 30โณ |
| Mid Size Showers | 47โณ x 32โณ, 60โณ x 32โณ, 30โณ x 47โณ, 30โณ x 60โณ |
| X-Large Showers | 60โณ x 36โณ, 72โณ x 36โณ, 72โณ x 48โณ, 60โณ x 48โณ, 40โณ x 79โณ |
These measurements refer to the inside of the showerโwhere you stand, move around, and enjoy your steam time. Of course, every bathroom is different, and thereโs always room to customize, but sticking to these general ranges can help keep things simpler and more cost-effective.
Shower Types and Dimensions
Now that youโve seen the standard sizes, letโs talk about the different types of showers and the dimensions that usually come with each one. Whether you’re updating a cozy hall bath or designing a luxurious primary suite, the style of shower you choose will influence how much space you needโand how the overall layout flows.
From sleek walk-in showers to practical tub-shower combos and everything in between, each type has its own space requirements. And understanding those differences can really help you make the most of your bathroom footprint.
Weโve broken it down by type to help you figure out what works best for your space, your style, and your day-to-day needs.
Walk-In Shower Dimensions
Walk-in showers are one of the most popular upgrades in modern bathroom remodelsโand honestly, we can see why. They look clean and minimal, theyโre easier to get in and out of (especially if you’re thinking ahead to aging-in-place), and they offer that spa-like experience right at home.
Whether you’re updating a hall bath or designing your dream en suite, a walk-in shower brings both form and function. That said, the size of your walk-in shower can really impact how it feels day-to-day, so getting the dimensions right from the start is key.
Standard Walk-In Shower Sizes
If you’re working within standard dimensionsโmeaning prefabricated pans or framed enclosuresโthese are the most common sizes:
Minimum Size: 32โณ x 32โณ
This is about as small as you can go while still being code-compliant in many areas. It works, but it may feel a little tight for some users.Comfortable Fit: 48โณ x 36โณ
A great mid-range option. It gives you more room to move around, shave, or even add a small bench.Spacious Option: 60โณ x 36โณ
This size is very common in primary bathrooms and works beautifully for tub-to-shower conversions.
Custom Walk-In Showers
If you’re working with a unique layout or just want something totally tailored, custom walk-in showers are where the fun begins. We design a lot of custom showers, especially for primary suites where people want a more open, luxurious feelโor need something specific for accessibility.
Custom sizing can start at around 36โณ x 48โณ and go up to 72โณ x 48โณ (or more), depending on the space available.
Want to include dual shower heads, body sprays, or a built-in bench? Thatโs where custom dimensions come in handy.
With custom designs, we also consider doorless layouts, half walls, floating benches, and full tile drainage systems.
Keep in mind that custom showers do take a little more planning, but the payoff is hugeโbetter flow, better comfort, and something that truly fits your space and your style.
Walk-in showers also need great drainage and smart waterproofing, which is something we always pay close attention to. Want to explore walk-in tubs too? Hereโs a helpful post we put together that breaks down what to expect.
Shower Pan Sizes
Choosing the right shower pan sets the tone for your entire shower layout. Itโs not just about sizeโitโs also about how the space functions and flows. Here’s a quick look at some of the most popular shower pan shapes and sizes we use in bathroom remodels.
Square Shower Pans
Square shower pans are a classic choice, especially for small to mid-sized bathrooms where space is limited but you still want a comfortable showering area. Their symmetry makes them easy to design around and they work well with sliding or hinged doors.
Popular sizes: 32โณ x 32โณ, 36โณ x 36โณ
These dimensions fit nicely into corner layouts or alcoves, and are a good fit for guest baths or compact master bathrooms.
Rectangular Shower Pans
Rectangular pans are super versatile and a favorite for walk-in showers or tub-to-shower conversions. They give you a little more elbow room and are often paired with frameless glass enclosures for a clean, modern look.
Common sizes: 30โณ x 60โณ, 36โณ x 60โณ
These work great in longer bathrooms and offer more space for shower benches or dual shower heads if you’re looking to upgrade.
Corner Shower Pans
Perfect for maximizing every square inch, corner shower pans are a smart pick for smaller bathrooms or powder rooms where space is tight but functionality is key. They tuck right into a corner and still give you enough room to move comfortably.
Typical sizes: 36โณ x 36โณ, 38โณ x 38โณ
These sizes offer just enough space for a comfortable shower without taking over the room.
Neo Angle Shower Pans
Looking for something a little more modern? Neo angle pans offer a stylish solution for corners, with an angled front that opens up the space and creates a sleek look. These are great when you’re aiming for a minimal, contemporary design.
Standard layout: 36โณ x 36โณ (each wall)
Size varies depending on the angle and door configuration
Tub Shower Combo Sizes
If youโre working with a smaller bathroomโor you simply want the flexibility of both a tub and a shower in one spaceโa tub-shower combo is a smart, space-saving solution. These setups are especially common in family bathrooms, guest baths, or condos where maximizing functionality is key.
The good news? Thereโs more than one way to design a combo. From the classic alcove tub to modern freestanding options, thereโs a style to fit just about every layout and look. Letโs walk through the most popular types and the sizes we typically work with:
Alcove Bathtub
The most common type found in older homes or guest bathrooms. Usually:
60โณ x 30โณ or 60โณ x 32โณ
Walk-in Shower (with tub option)
Want more comfort or accessibility? Check out our guide on walk-in tubs.
Retro Freestanding Tub Showers
A charming mix of old and new. These vary, but youโll often see:
55โณ to 72โณ in length
Paired with a ring shower curtain and floor-mounted risers
Wet Area Tub & Shower Dimensions
A โwet areaโ layout is when the tub and shower share the same waterproof space. These designs are trending right now and can look stunning in both large and small bathrooms.
Common configurations include:
Tub with adjacent shower: 72โณ x 48โณ or larger
Open wet area zone: custom-sized depending on your space
Shower Niche Dimensions
We love building in shower nichesโtheyโre practical, stylish, and make your daily routine so much easier. No more cluttered corners or hanging caddies. Plus, theyโre a great way to add a little design detail to your tile work.
There are two main types we typically install:
Technically yes, but itโs not always recommended. Exterior walls often contain insulation, and cutting into them can affect energy efficiency. We usually suggest placing niches on interior walls when possible.
Pre-formed and waterproof. Common sizes:
12โณ x 12โณ
12โณ x 20โณ
- 12โณ x 28โณ
Custom Shower Niches
Tailored to your needs. We typically design these based on:
Product size (shampoo bottles, razors, etc.)
Tile layout and spacing
Shower Rod & Curtain Sizes
If youโre going with a curtain over a doorโespecially for alcove or freestanding tubsโgetting the right size rod and curtain makes all the difference.
Standard rod length: 60โณ for alcove tubs
Curved rods: 60โณ with a 3โณ to 10โณ outward curve for extra room
Shower curtain size: 72โณ x 72โณ is the go-to

Shower Door Dimension
If youโre planning a glass shower, there are a few things to keep in mindโlike clearance, door swing, and the type of glass you choose. Frameless glass showers are super popular for their clean, modern look, but they do need precise measurements to ensure a proper fit and smooth functionality.
Youโll also want to think about day-to-day upkeep. Glass showers look amazing, but they can show water spots and soap buildup if not cleaned regularly. The good news? With the right habits (and a few easy tricks), keeping them sparkling is totally doable.
Check out our guide to cleaning glass shower doors for simple tips that actually work.
Sliding Shower Doors
47″ & 60โณ wide (standard) with two panels
Ideal for tubs or larger rectangular showers
Swing Door Shower Doors
Usually 22โณ to 36โณ wide
Needs space to open outwards (or inwards, if designed that way)
Custom Shower Enclosure
These are designed to fit your specific space
Often made from 3/8โณ or 1/2โณ thick glass
Frameless styles give a clean, open feel
