Clear glass = zero privacy in the bathroom
A glass Sexy Bathroom is 100% clear · passersby · neighbors in the condo tower opposite · housekeepers · children can all see in · the most sensitive moments of the day need privacy on demand
Switch bathroom glass from clear to frosted in 0.1 seconds (Smart Film / switchable PDLC film) — replaces blinds/curtains that trap mold · 360° water protection with Aquaris™ · compare Smart Film (applied over existing glass · zone privacy on the lower half saves 30–50%) vs Smart Glass (Tempered Laminated safety grade) · 36+ real projects: Pullman · Aman · Four Seasons · TAIT Sathorn 12
Why choose Smart Film · see the comparison with Smart Glass below ·
The glass-walled Sexy Bathroom is the trend across premium luxury homes / hotels / condos — but fully clear glass clashes with privacy · and blinds and fabric curtains in a bathroom accumulate mold · dust mites · musty odors from the constant high humidity.
Smart Film (switchable PDLC / PNLC film) and Smart Glass (switchable privacy glass) switch glass from clear to frosted with electricity · 360° water protection · a smooth surface that wipes clean and harbors no germs · blocks 99.99% of UV/IR · lasts 12–15+ years · This page compares the two options with an estimate for a 4 sqm bathroom — covering just the eye-level band (Center Strip) with Smart Film saves 30–50% · real projects: Pullman Hotels · Four Seasons Private Residences · TAIT Sathorn 12 · Botanica Villas, and 30+ more.
Clear ↔ frosted instantly · switch the moment a meeting starts or breaks · no need to draw blinds
Switch off instantly from wall switch / app / Smart Home · blocks light to protect furniture and TV screens
So seamless it looks like no film was installed · the hallmark of the InHouse install team
Thai brand owner · direct service with no middleman · Film 12+ · Glass 15+ yrs base · +50% Premium boost
Clear glass looks modern but creates new problems — Smart Film (retrofit) or Smart Glass (factory-built) solves the three key ones
A glass Sexy Bathroom is 100% clear · passersby · neighbors in the condo tower opposite · housekeepers · children can all see in · the most sensitive moments of the day need privacy on demand
A bathroom at 80%+ humidity · aluminum blinds/fabric/curtains accumulate mold, black mildew, dust mites, musty smells · must be taken down and washed every 1–3 months · risky for dust-allergy/asthma sufferers/young children · Smart Film has a smooth surface that doesn't hold moisture
A west/south-facing bathroom takes full UV · tiles fade · rubber seals perish · wooden bathroom furniture degrades · UV even harms your skin while bathing · Smart Film/Glass blocks 99.99% of UV/IR
Today's luxury home / 5-star hotel / villa trend uses the Sexy Bathroom clear-glass look as a signature feature · ordinary blinds/curtains make a bathroom look outdated · Smart Film/Glass switches clear↔frosted in 0.1 seconds = an eye-catching highlight
Switch clear ↔ frosted in 0.1s to suit the moment — a Smart Film advantage that frosted film cannot match
Glass frosts the instant you press the switch · 100% privacy · no walking over to draw a curtain · no worrying about neighbors in the tower opposite
Clear glass = full natural light · the bathroom feels bright and spacious · not stuffy · less mold from lingering moisture · saves energy
Fully clear glass · showcases the luxury bathroom design · marble tiles · a Hansgrohe shower · a signature feature ordinary homes don't have
Auto-frost · no bathroom light spilling out to disturb the bedroom · auto-triggered by a motion sensor / Google Home routine
Both use the same PDLC/PNLC technology — the difference is retrofit (film) vs factory-built (glass)
InHouse engineer recommendation: In a bathroom, glass safety (Tempered Laminated) is where Smart Glass wins — the glass breaks without falling, reducing injury risk in a slippery room · but if you want partial zone privacy (just the eye-level band) or a retrofit of an existing condo/home → Smart Film + Aquaris™ is far more cost-effective and just as water-resistant · new-build luxury villas → Smart Glass recommended · existing condos/homes → Smart Film recommended
The InHouse engineering team surveys your site free — recommending the zones that give the best value for your budget
A condo/two-story-home bathroom facing where people pass · neighbors · housekeepers · children · cover the full pane or an eye-level Center Strip
Shower-box glass · sliding glass dividing the wet/dry zones · cover the full pane for privacy while showering
A 0.5–2 sqm skylight above the shower / bathtub · apply it to block UV that fades skin while bathing + privacy at night
A 0.5–1.5 sqm glass window · Outdoor + Aquaris™ because it takes direct rain · opens and closes normally
A condo/luxury-home bathroom glass door · cover just the eye-level band so a faint silhouette shows (you know someone's inside) but no details

A luxury villa, Mueang Prachuap Khiri Khan, Prachuap Khiri Khan
The bathroom door is clear glass and looks beautiful, but you can see straight in. We wanted privacy without blinds that look cluttered and get water marks in the bathroom.
Press opaque to screen the view for instant privacy / a smooth, slat-free surface with no water marks, easy to maintain
"After installation I'm really impressed. One button and the glass turns frosted instantly; the bathroom is fully private yet still looks open and refined. No blinds to keep wiping water marks off. The crew finished the work and concealed the wiring so seamlessly."— Villa Owner · Prachuap Khiri Khan
A chilled-out natural-style riverside cafe, Bang Len District, Nakhon Pathom
The bathroom in the room has a curved glass wall. We wanted privacy when guests use it, but without blinds that look cluttered and keep collecting water marks — so we looked for smart film that installs seamlessly on curved glass.
Press opaque to screen the bathroom instantly in a single panel / a smooth, slat-free glass surface, easy to wipe with no marks
"After installation I'm really impressed. The crew fitted film onto the curved glass so seamlessly it looks like one with the glass; press clear to show off the bathroom design, press opaque and it's private instantly. The bathroom looks more upscale, and guests admire it a lot."— Venue Owner · UHURA by the River
A chilled-out natural-style riverside cafe, Bang Len District, Nakhon Pathom
We wanted the venue's glass bathroom to look as luxurious as a hotel, but it also had to be private when customers use it — so we looked for smart film that switches clear-to-opaque, without blinds that are hard to maintain.
Tap opaque to turn it private instantly / a smooth glass surface, easy to wipe, no slats for mold to cling to
"After installation I'm really impressed. Press clear and the glass bathroom looks spacious and luxurious like a hotel; press opaque and it's private instantly. Many customers love taking photos to post on social, and it's become a highlight of the venue — plus it's far easier to maintain than blinds."— Venue Owner · UHURA By The River
Single house, Soi Phibun Songkhram 22, Mueang District, Nonthaburi
The dressing-room window connected to the bathroom could be seen from outside the house. I didn't want blinds because the bathroom's damp and they'd grow black mold. I wanted something that stays open to daylight but can be pressed private instantly.
Press opaque for instant private screening / smooth film surface with no slats and no mold
"After installation I'm really impressed. One press and the window turns frosted to block the view instantly, while the dressing room stays open to daylight as before. No fussing over wiping blind slats. The crew finished the work so seamlessly."— Homeowner · Nonthaburi single house
Ladawan Village, Taling Chan District, Bangkok
The blinds in my bathroom grew black mold along the slats from the humidity, and wiping each slat is impossible. I wanted something that screens sightlines but is easier to care for than this.
Switch to smooth, mold-free smart film / switch opaque to screen sightlines in the bathroom instantly
"After installation the bathroom looks much cleaner — no blind slats for black mold to cling to. Clear mode gives an airy garden-court view; opaque gives full privacy. The crew finished the work very neatly."— Homeowner · Ladawan Village
Soi Yothin Phatthana 1, Bang Kapi District, Bangkok
My bathroom has glass walls and a clear glass door, so you can see in while using it. I didn't want blinds because the bathroom is humid and they'd grow mold and be hard to wipe. I wanted something I can turn private, yet still open onto the back garden view at normal times.
Switch opaque to a frosted screen instantly / a smooth surface wipes clean and won't grow damp mold
"After switching to InHouse Smart Film, the bathroom looks much more upscale. One press turns opaque for instant privacy, with no blinds to wipe water marks off or worry about mold. The smooth glass surface is very easy to wipe. In free moments I switch clear for the garden view. Love it."— Khun Pat · Homeowner
