Bathroom water filters
A bathroom filter has to do three things at once: treat the water, fit the space, not announce itself.
From ₹14,000. Final price after free survey. EMI from ₹1,167/month via Bajaj Finserv / Snapmint.
The problem this solves
What changes when the water is right.
Hair feels different. Dry. Brittle. The shower’s the same; the water isn’t.
Geyser efficiency drops. The 50°C bath ends up 35°C. Scale in the heating element.
CP fittings dull. Marble grout takes an orange line. The bathroom ages faster than the rest of the house.
Bathing on hard water dries skin. Soap doesn’t lather. Towels feel rough.
How we solve it
Sized to the water, the house, and the people in it.
Every Uniwater bathroom water filters starts with a free water test and a site survey. The chemistry decides the media. The household decides the capacity. The architecture decides where it goes.
Catalogue sizes are starting points, not the sale. Our 17-rule auto-suggest engine generates a bill of materials specific to your water analysis, pressure, and draw — not a generic SKU pulled off a shelf.
Engineered, not bought off a shelf.
Inside the vessel
The engineering, in section.
What the system looks like on the cutaway. Media bed, distributor, freeboard, control head — the visible engineering that decides what the water does over the next fifteen years.
The four-stage train
Sediment. Iron. Carbon. Softening.
What’s included
Everything to put it in. Everything to keep it running.
Engineered vessel + media
FRP or SS316 vessel, sized to your draw and chemistry. Media chosen for the specific problem.
Controls & valves
Manual or automatic regeneration. Pressure gauges and flow meters where they matter.
Installation
Plumbing, electrical, mounting, and commissioning. Documented before handover.
Water analysis
Pre-install and post-install parameter readings. Filed with your quote.
One-year warranty
All system components covered. Replacement, not repair-by-letter.
One-year AMC included
Monthly preventive service on Comprehensive / Premium tiers. Standard tier gets quarterly.
Where it goes
Five places it disappears.
BathSoft is engineered for real Indian bathrooms — tight shafts, low ceilings, finished interiors. Specified at site survey. Decided before tile.
False ceiling
Above the bathroom, hidden in service void.
Hidden niche
Recessed behind tile or shower glass — part of the bathroom, not on it.
Wall cabinet
In a service cabinet flush with the wall, behind a finish door.
Under-counter
In the vanity cabinet, beside the trap.
Utility room
For whole-house systems — plant area or garden corner.
Architectural patterns
How the system fits, on paper.
Section drawings of the install patterns we use most often for this system. Pre-tile, mid-construction, or as a retrofit — the right pattern is decided at survey, against the house.
01 · False-ceiling
Vessels in the void above the suspended ceiling. Equipment hidden until access panel removed.
04 · Plumbing duct
Vertical install in concealed riser shaft. Routes within existing infrastructure, no architectural intervention.
06 · Wall cabinet
Cabinet mounted ON the wall with serviceable doors. Finished interior, no construction needed.
07 · Wall niche
Recess cut INTO the wall, flush with tile. Architecture-grade — vessels become part of the wall.
Configurations
Three or four sizes. Decided by load, not by SKU.
We don’t expose part numbers. The configuration is decided at survey based on bathroom count, household draw, and water chemistry.
Mono
Single cylinder
Basic fittings. Single shower. Standard CP. Lowest demand.
Duo
Double cylinder
Rain shower with body jets, or two showers running together. Mid demand.
Trio
Triple cylinder
Master suite with steam, jacuzzi, multiple high-flow outlets. Highest demand.
