Tile Job Materials Guide: Tools & Materials for Every Project Type
Whether you're tiling a bathroom floor, a shower surround, a kitchen backsplash, or an outdoor patio, this guide covers every tool and material you need from start to finish — broken down by project type so you can plan and budget with confidence.
Quick Answer
Every tile job needs tile, thinset adhesive, grout, spacers, and a trowel. Beyond that, the project type determines whether you also need a wet saw, backer board, waterproofing, sealer, or specialty trim. Use the sections below to build a complete materials list for your specific project.

1What tools does every tile job need?
Regardless of the project type, you'll need most of the tools below. Individual project sections note when you can skip an item.
Cutting Tools
Manual snap cutter — sufficient for straight cuts on ceramic and standard porcelain tiles up to about 18". Affordable and portable.
Wet saw (tile saw) — required for porcelain, natural stone, L-cuts, notches, and any tile thicker than 3/8". Rent a 7" or 10" saw for large jobs; a tabletop model works for small projects.
Angle grinder with diamond blade — useful for notch cuts, outlet cutouts, and curves that a wet saw can't handle.
Tile nippers — for small nibble cuts and shaping around pipes or irregular edges.
Setting & Grouting Tools
Notched trowel — size depends on tile size. 1/4" × 1/4" square-notch for mosaic and small tile; 1/4" × 3/8" for 12"–16" tile; 1/2" × 1/2" for tiles larger than 16".
Grout float — rubber-faced float for pressing grout into joints.
Sponges & buckets — at least two buckets (one for mixing, one for clean water) and a large hydrophilic grout sponge.
Mixing drill & paddle — a corded or cordless drill with a mixing paddle for thinset and grout. Do not mix thinset by hand.
Spacers or leveling clips — standard cross spacers for consistent joints; leveling clips (e.g., Spin Doctor, Raimondi) for tiles 12" and larger to prevent lippage.
Layout & Safety
Chalk line — snap reference lines for your starting row.
Speed square & tape measure — essential for checking square corners and measuring cuts.
Laser level or 4' bubble level — critical for wall tile; useful for checking floor flatness and maintaining level rows.
Knee pads — floor installations require hours on your knees. Gel or foam pads are essential.
Safety glasses & ear protection — wet saws and angle grinders are loud and throw debris.
2What materials does every tile job need?
These materials appear in every project. The project-specific sections below call out when you need a particular variant (e.g., modified vs. unmodified thinset).
Tile
Order 10% extra for straight-lay patterns, 15% for diagonal or brick patterns, and 20% for herringbone or complex patterns. Always keep 2–3 spare tiles in storage for future repairs — exact dye-lot matches may not be available later.
Thinset / Adhesive
Modified (polymer-enhanced) thinset — the default choice. Better adhesion, some flexibility, and bond strength for floors and walls.
Unmodified thinset — use when installing over an uncoupling membrane like Ditra, or when the manufacturer requires it. It cures by losing moisture, which the membrane's fleece backing allows.
Mastic (pre-mixed adhesive) — acceptable only for wall tile in dry areas (e.g., backsplash). Never use for floors, wet areas, or large format tile.
Grout
Sanded grout — for joints wider than 1/8". The sand prevents shrinkage and cracking in wider joints.
Unsanded grout — for joints 1/8" or narrower, and for polished stone tiles where sand could scratch the surface.
Epoxy grout — stain-proof and waterproof. Ideal for showers, kitchen counters, and areas exposed to chemicals. Harder to apply and more expensive.
Sealer
Cement-based grout (sanded or unsanded) should be sealed after curing to resist stains and moisture. Epoxy grout does not need sealing. Natural stone tiles (marble, travertine, slate) should be sealed before grouting and again after installation. Glazed ceramic and porcelain tiles generally do not need sealing.
3Bathroom Floor
Tools Needed
Wet saw or snap cutter (wet saw preferred for porcelain)
1/4" × 3/8" notched trowel (standard 12"×12" tile)
Grout float, sponges, buckets, mixing drill
Spacers or leveling clips, knee pads, safety glasses
Materials Needed
Tile + 10–15% waste
Modified thinset mortar
Sanded grout (most bathroom floor joints are 1/8"+)
Cement backer board (CBU) — 1/4" thick for floors over plywood subfloor
Waterproofing membrane — recommended (liquid-applied like RedGard or sheet membrane)
Grout sealer + caulk for tub/wall transitions
Transition strip where tile meets other flooring
Bathroom Floor Tip: Waterproofing is strongly recommended even outside the shower area — bathroom floors see regular splashing, and moisture can wick through grout joints into the subfloor. A liquid membrane like RedGard over the backer board takes 1–2 hours and prevents expensive water damage later.
4What do you need to tile a shower or tub surround?
Tools Needed
Wet saw (required — shower tiles often include porcelain, stone, or glass mosaic)
1/4" × 1/4" trowel for mosaic; 1/4" × 3/8" for standard wall tile
Laser level or long spirit level — maintaining plumb and level rows on walls is critical
Hole saw / diamond core bit for showerhead, valve, and mixing handle cutouts
Materials Needed
Tile + 15% waste (walls have more cuts around fixtures)
Modified thinset for walls; unmodified over Kerdi or Ditra
Sanded or epoxy grout (epoxy is best for shower durability)
Cement backer board (1/2" for walls) or Kerdi board
Waterproofing membrane — mandatory for all shower surfaces (Kerdi sheet, RedGard, or Hydroban)
Shower pan liner or pre-formed shower base (for custom shower floors)
Caulk (silicone) for all inside corners and wall-to-floor transitions
Trim — Schluter Jolly or bullnose at exposed tile edges
Critical — Waterproofing: Every surface inside a shower must be waterproofed. This includes walls, floor, ceiling (if tiled), curb, and niche. Failure to waterproof is the #1 cause of shower failures. Shower floors must also slope toward the drain at a minimum of 1/4" per foot.
5Kitchen Backsplash
Tools Needed
Manual snap cutter or wet saw (snap cutter is often enough for subway tile)
1/4" × 1/4" V-notch or square-notch trowel (smaller tiles = smaller notch)
Laser level — essential for keeping the first row perfectly level
Oscillating multi-tool — handy for cutting around outlets
Materials Needed
Tile + 10% waste (backsplash areas are relatively small)
Pre-mixed mastic adhesive or modified thinset — mastic is acceptable for a dry wall application
Unsanded grout (most backsplash joints are 1/16" to 1/8")
No backer board needed — drywall or painted wall is fine for a dry backsplash
No waterproofing needed
Caulk where backsplash meets countertop (change of plane)
Trim — Schluter Jolly strips or bullnose for exposed side/top edges
Backsplash Tip: Kitchen backsplashes are one of the most beginner-friendly tile projects. The area is small, drywall is an acceptable substrate, and you often don't need a wet saw if you're using subway tile or smaller ceramics. Start here if it's your first tile job.
6Kitchen Floor
Tools Needed
Wet saw — most kitchen floors use porcelain or large format tile
1/4" × 3/8" or 1/2" × 1/2" trowel depending on tile size
Leveling system — strongly recommended for tiles larger than 12"
All standard setting & layout tools (see Section 1)
Materials Needed
Tile + 10–15% waste (kitchens have corners, islands, and cabinet cuts)
Modified thinset mortar
Sanded grout (floor joints are typically 1/8"+)
Cement backer board or Ditra uncoupling membrane over plywood subfloor
Waterproofing not required (recommended near dishwashers & sinks)
Transition strips where tile meets hardwood, carpet, or LVP
Grout sealer after curing
Large Format Tile Note: Kitchen floors often use 12"×24" or larger tiles. These require a 1/2" × 1/2" trowel, a leveling system, and back-buttering (applying a thin skim coat to the back of the tile in addition to troweling the floor) to achieve full coverage and prevent hollow spots.
7Fireplace Surround
Tools Needed
Wet saw or snap cutter — depends on tile material
1/4" × 1/4" or 1/4" × 3/8" trowel (fireplace tiles are often smaller or mosaic)
Laser level for maintaining straight rows on a vertical surface
Materials Needed
Heat-rated tile — porcelain, ceramic, or natural stone (NOT glass near the firebox unless rated for heat)
Heat-resistant thinset mortar (standard thinset within the mantel area; heat-rated thinset near the firebox)
Unsanded or sanded grout (depends on joint width)
Cement backer board over drywall (especially near firebox for fire safety)
No waterproofing needed
Metal or bullnose trim for exposed edges
Caulk at the hearth-to-surround joint (change of plane)
Heat Safety: Within 6" of the firebox opening, use heat-resistant thinset rated for high temperatures. Standard thinset is fine for the rest of the surround. Always check local building codes for clearance requirements around the firebox.
8What do you need to tile an outdoor patio or porch?
Tools Needed
Wet saw (required — outdoor tiles are porcelain or natural stone)
1/2" × 1/2" trowel (outdoor pavers are often large format)
Long straightedge or string line for checking slope and flatness
Rubber mallet for setting thick outdoor pavers
Materials Needed
Freeze-thaw rated tile — porcelain with water absorption below 0.5% (check the rating if you experience freezing winters)
Flexible / polymer-modified thinset — outdoor slabs expand and contract with temperature; flexible thinset prevents bond failure
Sanded grout with 3/16"–1/4" joints (wider joints handle expansion)
Concrete slab substrate — tile directly over concrete (no backer board)
Anti-fracture / crack isolation membrane (e.g., Ditra) — prevents concrete cracks from telegraphing through tile
Penetrating sealer — protects tile and grout from moisture, UV, and stains
Expansion joints with backer rod and caulk every 8–12 feet and at all perimeter edges
Outdoor Critical: The concrete slab must slope away from the house at a minimum of 1/4" per foot for drainage. Using non-freeze-thaw-rated tile in a cold climate will result in cracking and spalling within 1–2 winters. Always verify the tile's water absorption rating before purchasing.
9Entryway / Mudroom
Tools Needed
Wet saw (porcelain or natural stone is common for high-traffic entryways)
1/4" × 3/8" or 1/2" × 1/2" trowel depending on tile size
Leveling system recommended for large format tiles
All standard setting & layout tools (see Section 1)
Materials Needed
Durable, slip-resistant tile — porcelain with a textured finish is ideal for areas that see dirt, snow, and rain
Modified thinset mortar
Sanded grout (floor joints are typically 1/8"+)
Cement backer board or Ditra over plywood subfloor
Waterproofing recommended if the entry has an exterior door (snow/rain tracking)
Transition strips at doorways to other flooring
Grout sealer — entryways see heavy foot traffic and need stain protection
Entryway Tip: Choose porcelain tile with a DCOF (Dynamic Coefficient of Friction) rating of 0.42 or higher for slip resistance. Darker grout colors hide dirt better in high-traffic entryways. Consider a patterned or textured tile to mask wear and dirt between cleanings.

11Where should you caulk instead of grout?
This is one of the most commonly overlooked aspects of a tile job. Using the wrong material in a joint leads to cracking and water intrusion.
The Change-of-Plane Rule
Any joint where two planes meet must be caulked, not grouted. Caulk is flexible and can handle the slight movement between surfaces. Grout is rigid and will crack at these joints.
✅ Use Caulk
Where floor meets wall
Inside corners (wall to wall)
Where tile meets tub or shower pan
Where backsplash meets countertop
Around fixtures (toilet base, shower valve)
Expansion joints on large floors
✅ Use Grout
Between tiles on the same flat plane
Floor tile joints
Wall tile joints on a single wall
Backsplash tile joints
Pro Tip: Use color-matched caulk (same brand and color as your grout) so the caulked joints blend seamlessly with the grouted joints. Most major grout manufacturers sell matching caulk tubes.
12Pro Tips
- Always dry-lay your tile first — set tiles on the floor without adhesive to check the layout, centering, and cuts before committing. This catches problems when they're still free to fix.
- Mix tiles from multiple boxes — tile colors can vary slightly between production lots. Pull tiles from 3–4 boxes at random to distribute any color variation evenly across the floor.
- Back-butter large format tiles (>12") — apply a skim coat of thinset to the back of the tile in addition to the troweled bed for full coverage and maximum bond.
- Don't walk on freshly laid tile for 24 hours — let the thinset cure undisturbed. Wait 24–72 hours (check manufacturer's instructions) before grouting.
- Seal grout after it has fully cured (typically 28 days) — sealing too early traps moisture and can cause haze or discoloration.
- Keep leftover tile, thinset, and grout packaging — the brand, color code, and lot number make reordering or matching years later much easier.
