A custom shower can completely change how a bathroom feels. Done well, it looks clean, functions better day to day, and is easier to maintain than the old tub and tile setups many Long Island homes still have. Done poorly, it becomes a source of leaks, musty smells, and constant cleaning.
This guide is designed for Long Island homeowners planning a bathroom renovation and considering a custom shower, whether that means a walk-in shower, a tub-to-shower conversion, or a full bathroom re-layout. If you are working with a local team for your bathroom remodeling project, use the checklist below to make smarter decisions before demolition starts.
Why custom showers need more planning than you think
A shower is not just “tile and a drain.” It is a system that has to manage water, humidity, and daily wear. In Long Island homes, you also want to plan around busy households, limited bathroom count, and older construction that may need updates behind the walls.
The biggest wins come from getting four things right early:
- A layout that matches how you actually use the bathroom
- Waterproofing details that prevent leaks long-term
- Ventilation that clears humidity fast
- Storage and lighting that make the shower convenient, not cluttered
Step 1: Choose the right shower layout for your bathroom
Walk-in vs. traditional curb
A walk-in shower can feel open and modern, but it is not automatically “better” for every bathroom. The right choice depends on floor slope, splash control, and how much space you have.
- Curbed showers help contain water and are often simpler to keep dry outside the shower.
- Curbless showers can look sleek and improve accessibility, but they require careful floor planning, correct slope, and good water control.
If you want the clean look of curbless but worry about water escaping, talk through glass placement, drain type, and how the floor will be built up before you commit.
Shower size and clearance
A comfortable shower is not just about square footage. Consider:
- Door swing or sliding clearance
- Space to towel off without bumping into the vanity
- Where the shower entry sits relative to the toilet and door
- Whether two people might use the bathroom at the same time
Drain choice: center drain vs. linear drain
Drain selection affects both performance and the tile layout.
- Center drains usually require a four-way slope, which can impact large-format tile.
- Linear drains can simplify slope direction and work well with bigger tile or a cleaner look.
A good rule: choose the drain based on how the shower will be built and tiled, not just because it is trendy.
Step 2: Waterproofing decisions that prevent the most common failures
If there is one area where you do not want shortcuts, it is waterproofing. Leaks usually do not show up immediately. They show up months later as loose tile, stains on the ceiling below, or musty odors.
What “waterproof” actually means in a shower
Tile and grout are not waterproof. They are a wear surface. Your waterproofing strategy lives underneath the tile.
Key components to plan for:
- Waterproofing membrane system for walls and floor
- Proper slope toward the drain
- Sealed penetrations for valves, shower heads, and body sprays
- Bench and niche waterproofing details
- Correct transitions at corners and seams
Niches and benches: beautiful, but high-risk if built wrong
Shower niches and benches are popular for a reason: they add function and style. They are also common leak points when they are built without a clear waterproofing plan.
If you want a niche:
- Decide the niche size early so framing supports it correctly
- Plan tile layout so the niche looks intentional
- Confirm the niche will be sloped so water does not sit inside it
If you want a bench:
- Choose a design that can be waterproofed cleanly
- Make sure the top surface has a slope
- Consider how the bench affects the shower space and glass placement
Step 3: Ventilation that keeps the bathroom fresh
A gorgeous shower can still feel unpleasant if the bathroom stays humid. Ventilation is also what protects your finishes, paint, and woodwork from long-term moisture damage.
A simple ventilation checklist
- Bathroom fan sized appropriately for the space
- Fan ducted to the exterior, not into an attic or ceiling cavity
- Fan placed where it pulls humid air effectively (not blocked by doors)
- Timer switch or humidity sensor option, if you want hands-free control
- Make-up air plan, especially in tight homes
If your bathroom has had peeling paint, mildew at the ceiling line, or foggy mirrors that take forever to clear, treat ventilation as a must-have upgrade, not an optional extra.
Step 4: Storage that keeps the shower clean and clutter-free
Shower storage is one of those details you notice every day. When it is planned well, your shower feels calm and easy. When it is ignored, bottles pile up on the floor, and corners get grimy.
Storage options that work well
- Recessed niche for shampoo and soap
- Corner shelves that match the tile and feel built-in
- Built-in ledge for a cleaner look than multiple small shelves
- Shower caddy zones planned into the layout (yes, even that should be planned)
Think about who uses the shower and what they store. A household with kids might want wider, lower storage. A guest bath might prioritize simplicity and easy cleanup.
For design and finish choices, it can help to review options in person at a showroom and compare materials side by side. If you are local, consider visiting the showroom to explore finishes and hardware options in real lighting.
Step 5: Materials that look great and hold up to daily use
Tile: balance style with maintenance
Tile decisions should be made with real life in mind.
- Smaller tiles can add grip on floors, but they increase grout lines and cleaning.
- Large-format tiles reduce grout lines but require a flatter substrate and careful installation.
- Glossy tiles can feel brighter but show water spots more easily.
- Matte finishes can hide spots but may require different cleaning habits.
If your goal is lower maintenance, talk about grout type, tile texture, and how the shower will be cleaned weekly.
Fixtures: function first, then finish
Fixtures are where most homeowners want to “upgrade the look,” but function matters just as much:
- Pressure balance and temperature control
- Hand shower for flexibility and cleaning
- Placement that works for different heights
- Simple controls that guests can figure out
You can browse categories like faucets, fixtures, tile, and other finishes on the Products page to get a sense of the options that can be coordinated in a full bathroom build.
Step 6: Lighting that makes the shower feel bigger and safer
Many bathrooms rely on a single overhead light, which creates shadows and makes showers feel smaller.
A better plan often includes:
- A bright general light for the whole bathroom
- A shower-rated recessed light or fixture in the shower zone
- Vanity lighting that reduces shadows at the mirror
- Optional softer lighting for a spa feel
Lighting also helps with safety. You want clear visibility on the shower floor and at the entry point.
Step 7: Plan the rest of the bathroom around the shower
A custom shower is the centerpiece, but it cannot be planned in isolation. Confirm these details early:
- Vanity width and drawer clearance
- Toilet placement and comfort space
- Door swing conflicts
- Towel bar and hook locations
- Mirror size and storage needs
- Where outlets and switches will land
If you are updating more than one space in your home, it helps to coordinate finishes so the style feels consistent. Browse the Gallery to see how different bathroom styles pair tile, fixtures, and cabinetry.

|---|---|---|
| Shower layout (curb vs curbless) | Floor structure, splash control, accessibility | Water outside the shower, awkward entry, rework |
| Drain type (center vs linear) | Tile size, slope plan, desired look | Poor slope, standing water, messy tile cuts |
| Waterproofing approach | Wall system, niche/bench details, penetrations | Leaks behind tile, musty smell, damaged framing |
| Ventilation upgrade | Fan size, duct route, humidity habits | Mold risk, peeling paint, lingering odors |
| Storage plan | Who uses the shower, bottle count, and accessibility | Clutter, hard-to-clean corners, frustration |
| Tile and grout choices | Maintenance preference, slip resistance, style | Constant cleaning, slippery floor, stained grout |
| Fixture placement | User height, shower width, and control accessibility | Water spray issues, uncomfortable use, wasted space |
| Lighting plan | Bathroom size, ceiling height, and daily routine | Dark shower, shadows, space feels smaller |
Common mistakes to avoid in Long Island shower remodels
Picking tile before confirming the build details
Your tile selection should match the slope plan, drain location, and waterproofing system. If those are not decided, tile choices can create extra complexity or force compromises.
Skipping ventilation upgrades
If the bathroom fan is weak or poorly ducted, the shower will always feel damp, no matter how nice it looks.
Overdesigning storage
More niches and shelves are not always better. A single well-placed niche can look cleaner and function better than three small ones.
Not thinking through cleaning
A shower that looks stunning on day one can be annoying if it is full of tight corners, high-maintenance grout, and finishes that show every water spot. Plan for a shower you can actually keep clean with a basic weekly routine.
