When you're planning a small bathroom remodel, it's easy to start with the fun things. Tile. Plumbing fixtures. Vanity color. Lighting.

Those decisions matter, but they're usually not where I start.

In a small bathroom, every inch has a job to do. Before we get too far into what the room is going to look like, I want to understand how it's actually going to work. Where does the door swing? What does it come close to? Where are you going to put the things you reach for every morning? How will you turn on the shower without having to maneuver around a door?

They're little questions, but they're the details you feel every day once the bathroom is finished.

And in a smaller space, those little details add up quickly.

Start With the Way You Move Through the Bathroom

One of the smallest details we've worked through on a bathroom project involved the door.

We were incorporating storage into the room, but we needed to make sure the bathroom door still had enough room to open comfortably without competing with the cabinetry.

Rather than sacrifice the storage, we created a small offset that gave the door the clearance it needed.

But solving the clearance problem was only half of the decision. We also wanted that offset to look like it belonged there.

We continued the same molding from the storage along the wall behind it. Instead of looking like a strange bump in the wall that was created to accommodate the door, the detail became part of the millwork.

It's subtle. Most people walking into the finished bathroom probably aren't going to stop and say, "Look at that door clearance."

That's the point.

The door works. The storage works. And visually, everything feels cohesive.

Those are some of my favorite design decisions because you don't necessarily notice what we did - you just notice that the room feels right.

Your Shower Enclosure Changes How You Use the Space

The tub or shower enclosure is another decision that can seem primarily aesthetic until you start thinking through how someone actually uses it.

Not every tub needs a glass door.

A shower curtain can be a great solution, particularly when easier accessibility is important. There's no glass door to maneuver around, and you have flexibility in how much of the opening is accessible at one time.

In other bathrooms, a frameless glass door may make more sense. It keeps the shower visually connected to the rest of the room and can give the bathroom a more finished, custom feel.

But I don't want to choose between those options based only on which one looks better in a photo.

I want to know: How are you going to turn the water on? Which direction should the door open? What's going to be easiest to use every day?

On one project, we worked with the homeowner on a surround that added texture while still feeling cohesive with the rest of the bathroom. We paired it with a door rather than a curtain or crossing sliding doors, which also gave us better access to reach in and turn on the water.

That's a small functional consideration that can make a big difference every single morning.

And if we're using a hinged glass door, we're also thinking ahead about where that door will be supported. Those structural decisions need to happen during the design process—not after the tile is installed.

Plan Storage Around What You Actually Own

Storage is one of those things every homeowner needs, no matter the size of the house.

Bathrooms make that especially obvious.

You need a place for extra toilet paper. Shampoo and conditioner. Towels. Toothpaste. Skincare. Hair products. All of the things you reach for as part of everyday life.

So instead of designing the bathroom and then asking, "Where can we add some storage?" I prefer to work backward.

What do you need in this room, and where would it make sense for those things to live?

Medicine cabinets are one solution I like because they make use of vertical space and keep everyday essentials accessible without requiring everything to live in a vanity drawer or sit out on the countertop.

Depending on the bathroom, we may also incorporate storage that's hidden or storage that's intentionally visible and becomes part of the overall space plan.

Custom doesn't have to mean complicated. Sometimes it simply means being strategic about what needs a home before we decide where everything else goes.

When storage is planned well, you don't spend much time thinking about it.

You just know where your things are.

In a Small Bathroom, Every Decision Affects Another

This is where small bathroom design gets interesting.

The door affects the cabinetry. The cabinetry affects the storage. The shower enclosure affects how you move through the room. The placement of those elements affects what we can do everywhere else.

None of those decisions is especially dramatic on its own.

Together, they're the design.

That's why I don't like starting a small bathroom renovation with a pile of tile samples and trying to build the room outward from there. We can absolutely get excited about tile - I do - but first we need to make sure the bathroom works.

This is especially important in many of the older homes throughout La Mesa, Del Cerro, San Carlos, Allied Gardens, Fletcher Hills and the surrounding San Diego neighborhoods. These bathrooms often weren't designed around the way families use their homes today, and we may be working within an existing footprint where every inch counts.

That doesn't automatically mean the bathroom needs to get bigger.

Sometimes we just need to make the space we already have work harder.

Design the Bathroom Backward From Real Life

If you're getting ready for a small bathroom remodel, spend some time in the room before deciding what it should look like.

Pay attention to what frustrates you now.

Does the door get in the way? Where does clutter accumulate? What are you constantly reaching across the room to grab? Is there somewhere convenient for an extra towel? Can you reach the shower controls easily? What do you wish you didn't have sitting on the counter?

Those answers should become part of the design.

Because a successful bathroom isn't just one with beautiful tile and fixtures. It's one where the door clears the cabinet, the shampoo has a home, the shower works the way you need it to, and all of those little decisions come together without calling attention to themselves.

That's what makes a small bathroom feel intentional.
