The 5 Bathroom Design Trends Shaping Southern California Through 2030

Upwell Builders | Design-Forward Construction for STRs

Why Bathrooms Matter More Than You Think

In the short-term rental world, bathrooms quietly influence everything from photo performance to guest satisfaction. According to Airbnb data, the bathroom is the second most-viewed space in a listing after the bedroom. But while a bed can be made with new linens, a bathroom reveals how well a space is designed, built, and maintained.

Recent studies back this up:

  • AirDNA reports that STRs with recently upgraded bathrooms command an average of 14 to 22 percent higher nightly rates than similar listings.

  • Guesty’s analysis of reviews found that bathrooms are mentioned more frequently than kitchens in both 5-star and 3-star ratings.

  • Pinterest searches for “spa bathroom,” “earth-tone bathroom,” and “curved vanity” have doubled or tripled since 2023.

Guests use bathroom photos to decide where to stay. Hosts use bathrooms to stand out. Here are the design trends that are delivering both style and results across Southern California.

1. Warm Minimalism

Also called: Earthy Modern, Crafted Calm, Quiet Luxury

This look uses natural textures and neutral tones to create a clean, calm environment. Bone-colored plaster, floating vanities in wood or stone, matte fixtures, and soft lighting form the foundation.

Why it works for STRs:

  • Calms the space without feeling cold

  • Feels timeless in desert and coastal climates

  • Matte finishes clean easily and hide water marks

  • Works in both historic and modern homes

What the data says:

  • Pinterest searches for “earth-tone bathrooms” rose 135 percent in the past year

  • Zillow found that homes with spa-like bathrooms sell for up to 1.8 percent more

  • WGSN calls this trend “Crafted Minimalism,” and it’s gaining traction in design-forward hospitality spaces

2. Sun-Bleached Mediterranean

Also called: Soft Mediterranean, California Coastal, Whitewashed Revival

Inspired by Greek islands, Puglian villas, and Moroccan touches, this trend pairs white plaster or limewash walls with sand-colored zellige tile, aged brass, and arched mirrors.

Why it works for STRs:

  • Feels bright and clean without being stark

  • Adapts easily to Spanish Revival or modern coastal homes

  • Layers well with warm wood and soft textiles

  • Photographs beautifully in California light

3. Durable, Guest-Proof Finishes

Also called: STR-Ready, Performance-Driven Design

Bathrooms in short-term rentals face more wear and tear than those in private homes. The most successful STR bathrooms use materials that are both beautiful and resilient.

Best materials:

  • Quartz countertops for stain resistance and easy cleaning

  • Microcement or tadelakt for seamless, grout-free showers

  • Matte or honed tile to reduce glare and hide water spots

  • Solid fixtures from trusted brands to avoid breakage or leaks

What the industry says:

  • TurnoverBnB found that STRs with sealed or groutless surfaces have 24 percent fewer cleanliness complaints

  • Consumer Reports ranks quartz highest in durability and ease of maintenance

  • Designers on Dezeen and Dwell are calling tadelakt a top finish for wet areas, combining longevity with luxury

4. Tropical Modern

Also called: Palm Minimalism, SoCal Jungle, Clean Tulum

This look blends a fresh coastal palette with smart organic elements. Think green tile, wood slats, breezeblocks, white plaster, and subtle plant touches.

Why it works for STRs:

  • Adds personality without being overwhelming

  • Connects indoor and outdoor spaces

  • Appeals to wellness travelers and lifestyle-focused guests

  • Works especially well in properties with private patios or outdoor showers

Design momentum:

  • Fireclay Tile reports growing interest in sage, terracotta, and sea green tones

  • Boutique hotel brands like Habitas and Casa Cook are building entire design programs around this aesthetic

  • Google Trends shows “green bathroom tile” as a breakout search term since 2023

5. Sculptural Simplicity

Also called: Soft Deco, Curved Minimalism, Japandi Romance

This trend softens hard lines and adds texture through subtle curves, fluted elements, and warm neutral palettes. It is especially effective in compact bathrooms where every detail counts.

Key elements:

  • Fluted vanities or tile

  • Rounded mirrors and arches

  • Reeded glass panels

  • Soft brass or brushed nickel hardware

Why it works for STRs:

  • Makes small bathrooms feel elevated

  • Adds charm without clutter

  • Popular among design-conscious travelers and Instagram-heavy guests

Trend support:

  • CB2 and Reform are leading with fluted cabinetry across product lines

  • Pinterest lists “curved interiors” and “reeded glass” among its most saved bathroom trends

  • Design influencers report higher engagement on posts featuring soft sculptural bathrooms

What These Trends Have in Common

Across all five, the consistent themes are clarity, calm, and guest-focused design. These aren’t trends for trend’s sake. They are strategic choices that improve:

  • Listing photo performance

  • Guest satisfaction and reviews

  • Booking conversion rates

  • Property value and maintenance efficiency
