Bathroom Tile Layout Template (India): Setting-Out, Centre Lines & Cut Plan

A tiler on an Indian bathroom site chalking centre lines on a screeded floor, a laser level and boxes of 600x600 vitrified tiles beside a dry-laid first row

A bathroom that "looks off" almost never fails on tile quality — it fails on setting out. The slivers at one wall, the cut that lands dead-centre behind the mirror, the floor joint that misses the skirting by 20 mm: all of these are decided before a single tile is fixed, on the day the tiler strikes the lines. This document is the template that makes those decisions on paper first. It sits at the pre-tiling stage of the project, after waterproofing and screed, and is filled in by the site engineer or interior designer with the head tiler before any adhesive is opened.

This is the setting-out template in the Studio Matrx bathroom hub. Use it alongside the bathroom design checklist for India for the wider fit-out sequence, the bathroom flooring guide for substrate and slope, the bathroom quality inspection checklist for the sign-off, and the ceramic tile IS standards for the tile spec itself.

Caveat first. This template is a starting point, not a shop drawing. Every bathroom has its own dimensions, drain position and door swing. Dry-lay and confirm the grid against the actual room and the fixed positions of WC, drain, niche and mirror before you commit, and check the tile spec and workmanship against the contract, IS/NBC provisions and a licensed professional.

How to use this document

Fill it in before tiling starts, standing in the finished (screeded, waterproofed, cured) room with the tiler:

Confirm the tile size and joint width from the spec, then compute tiles-per-square-metre.
Establish a single datum: one level line around the room, struck at a convenient height (commonly 1000 mm above finished floor level, FFL) with a laser or water level. Every wall course is measured from this one line — never from the floor, which slopes.
Identify the focal wall — the first surface the eye meets on opening the door, usually the WC / shower wall — and set full tiles there.
Strike the two centre lines on the floor (perpendicular chalk lines through the room centre) and dry-lay outward to see where cuts fall.
Adjust the start point so no cut is thinner than one-third of a tile; shift the whole grid rather than accept a sliver.
Record every decision in the setting-out table below and get the tiler to sign it.

Setting-out decision table (the core template)

Copy this table into your site file and complete one row per wall plus the floor. The logic: pick a datum line you measure from, decide the full-tile start point (so the good tiles land where they are seen), and then you already know where the cuts land — push them to the least-seen corner, into the internal angle, or under the vanity.

Surface	Datum line to work from	Full-tile start point	Where the cuts land	Notes / India specifics
Focal wall (WC / shower wall)	1000 mm horizontal datum; vertical centre line of the wall	Full tile centred, OR full tile at the more visible internal corner	Both ends equally, or the concealed corner	This wall sets the whole scheme — get it symmetrical; align niche to a joint
Door / entry wall	Same 1000 mm datum	Full tile at the door architrave side	Behind the door leaf / hidden corner	Cuts vanish when the door is open
Vanity / basin wall	1000 mm datum; centre line of the basin	Full tile centred on the basin / mirror	Outer edges of the wall	Keep tap and waste holes within a tile, not on a joint
Window / short wall	1000 mm datum	Full tile under the sill or centred on the window	Reveals and corners	Match reveal cuts left-to-right so the window looks framed
Floor	Two centre lines struck 90° apart through room centre	Full tile at the door threshold and along the sight line to the WC	Against the least-seen wall, under the vanity	First floor course under the wall skirting drives the wall grid if joints are aligned
Skirting / dado band	The 1000 mm datum and the floor grid	Skirting/dado joints line up vertically with wall-tile joints	N/A — full pieces, mitre at corners	Skirting 100–150 mm; dado band height set to a full course, e.g. 900 or 1200 mm

Coordinating skirting, dado, threshold and slope

These four details are where amateur jobs give themselves away. Plan them on the grid, not on the day:

Skirting / dado. Whether you run a full-height wall tile or a skirting-plus-dado band, the vertical joints must sit directly above the floor joints so the eye reads one continuous line from floor up the wall. Set the dado top to land on a full course — do not finish a band with a 40 mm sliver.
Threshold. At the door, the bathroom FFL is usually 10–20 mm below the adjoining room to contain water. Detail the threshold tile or stone strip as a deliberate full piece, sloping back into the bathroom, and decide now whether the floor grid runs through the doorway or stops at a clean threshold joint.
Slope to drain. Indian wet floors are laid to fall — commonly 1:80 to 1:100 (about 10–12 mm per metre) — toward the floor trap. The slope is built into the screed, not the tile thickness, so smaller floor tiles (300×300 or 300×600, or mosaics in the shower) sit flatter on the fall than a large 600×600. Plan the drain to fall on a tile joint or the centre of a tile, never awkwardly across one corner. Coordinate this with the flooring guide.

Tile quantity estimation table

Estimate materials from the grid, not by guesswork. Tiles per sqm = 1 ÷ (tile area in m²); add wastage for cuts, breakage and future replacements (10% for a plain rectangular room, 12–15% for many cuts, diagonal lay, patterns or small rooms), then round up to full boxes. Rates below are indicative and vary by city, brand and finish.

Area to tile	Tile size	Area per tile	Tiles / sqm	Nett area	+ Wastage	Tiles needed	Boxes (approx.)
Bathroom floor	300×300 mm	0.09 m²	11.1	4.0 m²	12%	50	5 boxes (10/box)
Bathroom floor	600×600 mm	0.36 m²	2.78	4.0 m²	12%	13	4 boxes (4/box)
Wall — full height	300×600 mm	0.18 m²	5.56	22 m²	12%	137	30 boxes (5/box)
Shower niche	300×300 mm	0.09 m²	11.1	0.6 m²	15%	8	round to 1 box
Skirting band (100 mm)	strips ex 300×600	—	—	10 rm	10%	~19 rm of strips	confirm on site

Worked example. A 1.8 m × 2.2 m floor = 3.96 m², call it 4.0 m². In 600×600 that is 4.0 × 2.78 = 11.1 tiles; add 12% = 12.4, round to 13 tiles. At 4 tiles per box you buy 4 boxes and keep the offcuts as spares. Always buy floor and wall from the same batch/shade number and keep two to three spare tiles boxed for the client.

Golden rules table

These are the non-negotiables. Print them and pin them at the tiling station.

Rule	Why it matters	The failure it prevents
Start from the focal wall	The eye lands there first on opening the door	A cut tile greeting you at the entrance
No sliver thinner than 1/3 of a tile	Thin cuts crack, pop and look accidental	Fragile 20 mm strips at a wall or corner
Align floor and wall joints	One continuous grid reads as deliberate	Joints that "miss" at the skirting line
Work from a datum, never the floor	The floor slopes to the drain; the datum is level	Wall courses that drift up or down
Plan niche, mixer, waste and accessories on the grid	Fixings look designed, not drilled at random	A shower niche or tap boss split across a joint
Balance the cuts	Equal cuts at both ends read as symmetry	One full tile and one sliver on the same wall

Common mistakes

Tiling off the floor line. The floor falls to the drain, so any course measured up from it climbs or dips. Always work from the level datum.
Forgetting the fittings. Mark the WC, mixer, shower valve, niche and towel-rail positions on the setting-out drawing so no boss or waste lands on a joint or in a cut.
Ignoring the door view. Set the grid for the person standing in the doorway, not for the wall you happen to start on.
Under-ordering. No wastage allowance means a second batch in a different shade. Order 10–15% extra and keep spares.
Mixing batches. Different shade / calibre numbers show as banding under bathroom lighting — check every box before laying.
Slope as an afterthought. Build the fall into the screed and plan the drain onto a joint; do not chase it with adhesive thickness.
