Bathroom design continues to evolve rapidly, and the National Kitchen and Bath Association (NKBA) 2021 Design Trends report offers valuable insights for builders planning new home projects and renovations. Based on survey responses from 716 design and construction professionals, the report highlights key shifts in bathroom sizes, materials, technology, and aesthetics that will shape residential construction through 2021 and beyond. Understanding these trends helps builders make informed decisions when designing a luxurious master suite bathroom that meets modern homeowner expectations.
Bathroom Size, Layout, and Spatial Trends
Primary Bathrooms Are Getting Larger
The NKBA survey reveals a clear shift toward larger primary bathrooms. According to the data:
- 42% of professionals expect primary bathrooms to become somewhat larger (25% or less increase in size)
- 32% believe bathroom sizes will remain about the same
- 23% anticipate significantly larger bathrooms (more than 25% increase)
- Only 1% see bathrooms becoming smaller
This trend mirrors findings from homeowner surveys showing that limited bathroom space remains the biggest frustration for many homeowners. Builders who allocate additional square footage to primary bathrooms gain a competitive advantage in the market.
The Bathtub Dilemma
One of the most significant layout decisions involves the bathtub. While 60% of professionals see homeowners opting for bathtub removal to free up space, 40% expect homeowners to demolish walls and expand bathrooms instead. Generational preferences also play a role. For Millennials (ages 23 to 38), 59% of professionals believe connecting the closet directly to the bathroom is the most popular option, creating a seamless dressing and bathing suite.
These layout decisions directly impact how builders approach strategic bathroom remodeling projects, where space planning and waterproofing integration are critical.
Smart Technology and Bathroom Innovation
Technology integration in bathrooms is growing, but homeowners want it to be useful without being intrusive. As one NKBA survey respondent put it, “tech that is useful, that is helpful, but not highly intrusive (practically invisible) will be huge.”
Top Smart Bathroom Technologies
The NKBA survey ranked the following smart technologies in order of expected popularity over the next three years:
- Smart temperature control for floors and showers
- Water conservation technology
- Motion-sensor controls for lighting
- Leak detection systems
- Preset lighting schemes for different times of day
- Mobile apps to start showers remotely
Lighting Technology Trends
Lighting remains a critical element in bathroom design, and technology integration is becoming standard. More than 50% of surveyed professionals identified the following as the best lighting choices:
- Lighting integrated into mirrors
- Dedicated shower lighting
- Recessed ceiling lights
- Sconces and wall-mounted lights
These lighting types should incorporate dimmer switches, motion sensors, or connected voice-controlled systems. Smart mirrors with backlighting and built-in electrical outlets are also gaining popularity, with professionals predicting they will dominate bathroom design over the next three years.
Materials, Finishes, and Product Selections
Countertop and Vanity Trends
Quartz has taken the top spot for bathroom vanity countertops, following the same trajectory seen in kitchen design. Lighter countertop colors remain the preferred choice among homeowners. When it comes to vanities themselves, several key trends emerge:
- Medium-tone colors are gaining popularity over stark white or dark finishes
- Floating or wall-mounted vanity installations are increasingly preferred
- Flat panel or slab door styles dominate over raised panel options
- Full painted wood and full wood grain are the most popular facing materials
- Decorative knobs and pulls are preferred over touch-open mechanisms or finger pulls
Sink and Faucet Selections
Pedestal sinks are nearly extinct in new bathroom design. Only 3% of professionals see homeowners wanting a pedestal sink in 2021 or beyond. Undermount sinks take the lead at 77%, with white vitreous china as the dominant material choice.
In faucet finishes, matte black has emerged as the dominant choice for 2021 and beyond. The top finishes are:
| Finish Type | Popularity Ranking | Key Characteristics |
|---|---|---|
| Matte Black | 1 (Dominant) | Modern, contemporary appeal, hides water spots |
| Nickel (Brushed and Polished) | 2 | Versatile, traditional to transitional styles |
| Chrome (Brushed and Polished) | 3 | Classic, budget-friendly, easy to match |
| Oil-Rubbed Bronze | 4 | Warm tones, traditional designs |
| Brushed Gold/Brass | 5 (Rising) | Luxury statement, pairs with matte black |
Manufacturers have expanded plumbing finish offerings significantly, with matte black leading the charge. Builders should consider offering multiple finish options to accommodate varied homeowner preferences.
Shower Design, Flooring, and Finishing Details
Shower Configuration and Features
The trend toward shower-only bathrooms continues. Homeowners increasingly prefer separate tub and shower configurations or showers alone. For those choosing showers, several specifications are emerging:
- Large-format tiles for shower walls, minimizing grout lines
- Clear shower glass, not frosted or decorative finishes
- Clean, subtle, and minimalist shower enclosures
- Showers sized for two people
- Zero-threshold showers gaining but not yet replacing traditional swing doors
Accessible and Specialty Shower Features
The NKBA survey highlights that accessible features are leading shower innovations. Eighty percent of professionals expect built-in shower benches to be the most popular shower feature, and 61% see grab bars becoming standard. Other popular specialty features include:
- Rain showerheads from above
- Steam generators for spa-like experiences
- Handheld shower wands
- Body spray jets
When homeowners do choose a tub, freestanding and soaking tubs made from composite, resin, or acrylic materials are the preferred options.
Flooring and Design Styles
Heated flooring dominates bathroom comfort features. A substantial 77% of professionals see heated floors as essential, with ceramic and porcelain tile as the preferred flooring materials. Contemporary design takes the top spot for most popular style over the next three years, with 57% of professionals expecting this to dominate. Transitional style follows closely at 53%, with organic and natural design claiming third place and rising rapidly in popularity, particularly among Millennials.
In terms of color palettes, professionals continue to favor whites and off-whites as primary choices, followed by:
- Whites and off-whites
- Grays (cool and warm tones)
- Blues (navy, teal, and soft blues)
- Beiges and bones (warm neutrals)
Style Blending and the Organic Trend
The most interesting development in bathroom design styles is the blending of multiple aesthetics. As one NKBA professional noted, “designs are evolving to include items from several different styles. For example, a modern bathroom may have elements of organic design included, or a touch of mid-century. The blended styles are becoming more prominent.” This trend gives builders and designers more freedom to combine elements from various design languages, creating unique bathrooms that appeal to a wide range of buyers. For builders looking to stay ahead of these evolving preferences, reviewing top 2020 bathroom design trends provides useful context for how these patterns have developed.
Mirror Technology and Bathroom Accessories
Mirrors in modern bathrooms are no longer simple reflective surfaces. Backlit mirrors with integrated lighting have become standard expectations, while smart mirrors with built-in defoggers, Bluetooth connectivity, and digital displays are gaining traction. Electrical outlets integrated into mirrors or medicine cabinets provide convenience for grooming appliances. Builders should plan for the necessary electrical rough-ins during the framing stage to accommodate these features without requiring surface-mounted conduits.
Storage Solutions and Organization
Homeowners increasingly demand smart storage solutions in bathrooms. The trend toward larger vanities with deep drawers, pull-out organizers, and integrated compartments reflects the desire for clutter-free countertops. Medicine cabinets are evolving into recessed storage systems with integrated lighting and electrical outlets. Builders should consider specifying:
- Deep soft-close drawers for toiletries and towels
- Pull-out hampers and waste bins within vanity cabinets
- Recessed wall niches in shower areas for shampoo and soap
- Towel warming drawers and heated storage racks
- Custom linen towers or built-in cabinetry for additional storage
Ventilation and Moisture Management
As bathrooms become larger and incorporate more technology and fixtures, proper ventilation becomes increasingly critical. Builders should plan for:
- Humidity-sensing exhaust fans that activate automatically
- Quiet-rated fans (1.0 sone or less) for primary bathrooms
- Proper duct sizing and routing to exterior vents rather than attics
- Continuous ventilation strategies for bathrooms without windows
- Integration with smart home systems for automated moisture control
These considerations not only improve comfort and air quality but also protect the building envelope from moisture damage over the long term.
Key Takeaways for Builders Planning 2021 Bathroom Projects
The NKBA 2021 Design Trends report provides actionable intelligence for builders. By incorporating these trends into project planning, builders can deliver bathrooms that resonate with current buyer preferences while maintaining functional durability.
Priority Action Items
- Plan for larger primary bathroom footprints where lot sizes and budgets allow
- Incorporate rough-ins for heated flooring, smart controls, and shower features
- Specify quartz countertops with lighter color palettes for vanities
- Offer matte black and mixed-metal finish options for plumbing fixtures
- Design showers with built-in benches, clear glass enclosures, and dual-user dimensions
