What I Tell Clients Before They Spend $30,000 on a Bathroom

Key bathroom renovation lessons (mistakes to avoid + what to do instead)

Shower mixer position

• Avoid: placing the mixer directly under the shower head. You’ll step into cold spray just to turn the water on.
• Do instead:
  • Place the mixer beside the shower (on a side wall) or on the opposite wall.
  • Make sure you can adjust the temperature without getting wet:
    • Side wall: adjust temperature with one hand while water runs past you.
    • Opposite wall: set it from outside the shower, then step in once it’s ready.

Shower head height

• Typical wall-mounted range: 77–81 in.
• Adjust for household height so nobody has to crouch.
• If you like rain showers, still include a handheld shower:
  • Fixed rain heads make it harder to rinse walls/floor.
  • A handheld option helps on days you don’t want to wash hair.
  • Adjustable rails are useful when multiple people use the bathroom.

Built-in shower storage (don’t “design it later”)

• Plan and build niches/ledges/recess shelving during waterproofing + tiling (not after).
• Measure your tallest bottles, and consider how many people share the shower.
• Trade-offs:
  • Niche: needs enough depth in the wall.
  • Ledge: easier to build but it projects into the shower.
• Slope the shower floor slightly toward the shower to prevent pooling.
• Same idea for other flat surfaces:
  • Direct water back toward the shower for curbs, window sills, and ledges.

Drain + floor tile strategy

• Choose drain type and tile together:
  • Center drain: requires slope from multiple directions; smaller tiles tend to follow better.
  • Linear drain: allows slope in one direction; larger tiles can work better.
• Ensure the shower floor slopes properly to avoid puddles.
• Also ensure water stays inside the shower:
  • For open showers, make sure the enclosure is deep enough and the glass extends far enough.
  • Avoid pointing the shower head directly at the opening.
  • Note: open showers can soak floors/bath mats (example cited: an Airbnb).

Open vs enclosed shower (comfort + warmth + containment)

• Open showers can feel colder because they don’t trap warm air/steam like enclosed showers.
• In colder climates, you may need extra heat—or skip open showers.
• A slightly smaller, well-contained, warm shower can feel more luxurious than a huge one that doesn’t perform.

Shower-over-bath vs space-saving choices

• If space is tight but you want both: shower over bath is typically better than trying to squeeze both separately.
• Pick a bath that’s comfortable to stand in:
  • Baths with more vertical end give more usable floor space.
  • Curved sloping ends reduce usable space.
• Check drain placement:
  • Prefer center drain or position so you’re not standing on the drain end.

Bath material + longevity

• More rigid options: porcelain enamel steel, stone resin, cast iron.
  • Cast iron is very heavy (installation considerations).
• Acrylic can work, but:
  • Quality/support vary widely.
  • Thin/poorly supported acrylic can flex, pulling silicone joints over time and allowing water behind the bath.
  • If choosing acrylic, verify reinforcement and whether it requires a frame/ledger/mortar bed.

Bath/shower screen design

• A large fixed glass panel can:
  • Be harder to reach taps with,
  • Make it more difficult to bathe children,
  • Complicate tub cleaning.
• For compact bathrooms:
  • Consider a hinged screen or a properly fitted curtain.

Surface/material regret: tile, stone, finishes

Marble and natural stone realities

• Marble is calcareous/porous:
  • Acidic products can dull/etch it.
  • Ongoing wet use plus products can cause it to “wear over time.”
• Sealing helps with staining resistance but is not stain-proof.
• Magazine/luxury looks usually assume professional maintenance.
• If you want lower maintenance:
  • Choose marble-look porcelain.
  • Before ordering, lay out multiple tiles to check how vein patterns repeat.
• Other materials with similar concerns:
  • Cement tiles and microcement may need strong protection.
• Always confirm:
  • Approved for wet areas
  • Whether it needs sealing, how often, and expected maintenance

Tile surface + grout considerations

• Very textured tiles and heavily grouted surfaces can trap:
  • Soap scum and mineral deposits
• Uneven surfaces and grout amount matter more if easy cleaning is a priority.
• Dark finishes in hard-water areas:
  • Mineral “chalk” buildup shows more easily.
  • Applies to dark tiles, dark tapware, and grout color.
• Grout color caution:
  • Bright white may fade/yellow unevenly.
  • Very dark grout can fade unevenly and make joints more prominent.
  • Mid-tone is generally more forgiving—but verify with a real sample beside the tile (not only packaging color).

Vanity/bathroom storage mistakes and fixes

Vanity layout choices

• Prefab vanities with two doors and no drawers often lead to awkward deep storage once plumbing takes the center.
• Prioritize drawers for day-to-day convenience (pull-out visibility).
• Pedestal sinks:
  • Great in powder rooms, but usually limited storage and counter space in main bathrooms.
  • In small spaces, consider a narrow wall-hung vanity—even shallow drawers can beat a pedestal.

Storage should be “at the point of use” (NKBA)

• Core idea: you should be able to reach:
  • Clean towel from the shower,
  • Toilet paper from the toilet,
  • Daily products from the basin
• A recessed medicine cabinet keeps items at eye level without cluttering the countertop.

Plan power before cabinetry

• If you use electric toothbrush/hair dryer:
  • Ask the electrician about a compliant outlet in/near the vanity or medicine cabinet so charging is out of sight.
• Plan outlet positions with the electrician before cabinetry is installed.

Vanity height + sink compatibility (NKBA)

• Typical vanity height is about 36 in, but the key measurement is the finished basin height.
• Vessel sink rule: if you place a vessel sink on a standard vanity, the rim may be too high; the vanity may need to sit lower.
• NKBA range: 32–43 in, depending on household.
• Tap and basin must match:
  • If the spout doesn’t reach the bowl, hands hit the back.
  • If the spout sits too high over a shallow basin, splashing happens.
• Basin shape matters:
  • Very flat bottoms + sharp corners can trap toothpaste/residue, increasing cleaning.

Space around the bath matters

• If a freestanding bath is pushed near a wall:
  • Leave about 8 in so you can clean/reach behind it.
  • If you can’t reach, the gap becomes a dust/hair collection zone.
• If you can’t keep that clearance:
  • Consider back-to-wall or back-to-corner baths instead.

Jetted baths: don’t buy a fantasy routine

• Jets are only worth it if you’ll genuinely use and maintain them.
• They’re harder to clean/maintain than standard baths.

Layout + privacy + ventilation/paint/lighting

Open toilet vs privacy expectations

• Open toilet concepts can feel fine in hotels, but often fail in real daily use for shared households.
• Light/sound/smell travel into the bedroom, especially when schedules differ.
• (Noted in reference: this trend is increasingly seen in new builds in Australia, but the source says it “doesn’t make much sense” day-to-day.)

Barn doors and privacy

• Barn doors often leave gaps and don’t provide bathroom privacy like:
  • Properly fitted hinged doors, or
  • Pocket doors

Separate toilet (if multiple users)

• If several people share the bathroom and space allows:
  • A separate toilet improves functionality (one person can shower while another uses the toilet).
• Don’t cram it into a tiny space.
• NKBA suggested comfortable toilet compartment: about 36 in by 66 in.
• Plan privacy from the start (avoid relying on a sliding panel that never fully closes).

Ventilation is not an afterthought

• Signs ventilation is insufficient:
  • Mirror stays fogged too long
  • Mold returns repeatedly
• Rule of thumb (Home Ventilating Institute):
  • Bathrooms up to 60 sq ft generally need at least 50 CFM (~24 L/s).
  • Larger bathrooms require more based on local requirements.
• Ducting matters:
  • Long ducts with bends reduce airflow.
  • Vent moist humid air outside, not into roof space.
• For better automation:
  • Use a timer or humidity sensor so the fan runs after you leave.
• Large bathrooms with shower/toilet at opposite ends:
  • Ask the contractor whether you need more than one extraction point.

Paint selection for bathrooms

• Avoid traditional flat/matte paints—they struggle in humid rooms.
• Prefer satin or semi-gloss, and note there are now matte/low-sheen bathroom-specific paints.
• Examples mentioned:
  • Dulux Wash and Wear Kitchen and Bathroom (matte finish)
  • Benjamin Moore Aura Bath and Spa (matte finish)
• Ensure paint is approved for humid bathroom conditions (don’t choose based on sheen alone).
• If unsure visually, use a Room Visualizer app to test finishes/styles in your actual space.

Lighting that flatters faces (not just “looks nice”)

• Avoid downlights directly above/behind you—they create shadows under eyes/chin and can make you look tired.
• Better options:
  • Sconces on either side, or
  • Lighting above the mirror
  • LED mirror that directs light toward your face
• Keep task lighting separate from general lighting:
  • Bright, even light for getting ready
  • Lower brightness for nighttime use

Tile ordering and batch-matching tips

• Don’t assume one tile order is enough:
  • You need extras for cuts, breakages, pattern matching, and future repairs
• Tile batches can vary:
  • Color/sizing differences become obvious once installed.
• For natural stone or varying tiles:
  • Lay out several tiles before ordering to check vein/pattern repetition.
  • Ask the installer to mix tiles from different boxes during installation.
• Save spares:
  • Keep labeled extra tiles after the renovation for future repairs.
