How to choose porcelain tile for floors and walls

How to choose porcelain tile for floors and walls

Porcelain tile combines long life with a wide range of looks. This step-by-step how-to helps homeowners, condo owners, contractors and DIY renovators choose the right porcelain tile: define the room use, verify technical specifications, pick finish and format, test take-home samples, assess installation needs, and confirm warranties. Use the checklist and the stop points where you should call a professional to avoid costly mistakes.

What porcelain tile is and where it excels

Porcelain is made from dense, refined clay fired at high temperatures to create a hard, low-porosity tile that resists moisture, stains and heavy foot traffic. Those qualities make porcelain a strong choice for bathrooms, kitchens, high-traffic areas and some exterior uses when the product is rated for outdoor conditions. For a concise technical overview, see Flooring Canada and manufacturer advice from Daltile. What Is Porcelain Tile, Porcelain Tile for Walls & Flooring.

Step 1: define the room use and required performance

Before you look at colours and textures, answer where and how the tile will be used. The site and intended use narrow your options and set minimum technical requirements.

• Is the tile for a floor or wall, interior or exterior?
• Will it be in a wet area such as a shower, bath, entry or kitchen?
• What traffic level do you expect: light residential, heavy residential or commercial?
• Will pets, children or heavy furniture affect durability needs?
• Will you use underfloor heating or must you meet condo soundproofing bylaws?

Porcelain offers many product variations, but not every porcelain tile is suitable for every application. Solidshape’s selection checklist is a useful reference when matching tile type to room function. How to Choose Porcelain Tile.

Decision checklist for room use

• Floor or wall?
• Interior only or exposed to freeze-thaw?
• Frequently wet area?
• Condo soundproofing required?
• Underfloor heating required?

Step 2: check the technical specs that determine suitability

Ask the retailer or consult the product data sheet for these specifications. Each one affects safety and longevity.

• Water absorption, which confirms low porosity and suitability for wet or exterior use. Porcelain’s low water absorption helps prevent frost damage and staining; do not assume all porcelain is rated for freeze-thaw exterior use. Verify the manufacturer statement for outdoor suitability. What Is Porcelain Tile, Daltile.
• PEI or wear rating to match durability with traffic levels. For hallways, kitchens or commercial spaces, request a higher wear classification. Solidshape explains how to match PEI to location. Solidshape.
• Slip resistance for wet areas and exterior walks. Ask for the published slip rating and, when possible, test a sample wet and dry to evaluate traction.
• Glazed versus colour-body. Glazed tiles have a surface finish and printed looks, while colour-body porcelain has the pattern and colour through the tile. Colour-body porcelain masks chips better; glazed porcelain offers more surface textures and printed effects. Manufacturer guidance helps you decide. Daltile.

Water absorption and exterior use

Low water absorption prevents frost damage in exterior installations and reduces the risk of staining indoors. Confirm the specific water absorption number and the manufacturer’s statement on freeze-thaw suitability before planning outdoor projects.

PEI or wear rating and traffic expectations

PEI or wear classification tells you how a tile will stand up to foot traffic. For heavy-use residential or commercial areas choose a tile with a higher wear rating and discuss tougher glazes with your retailer.

Slip resistance and wet-area safety

Slip ratings matter for showers, bathroom floors and exterior steps. If you must meet building codes or condo standards, request the tile’s published slip rating and keep that documentation with your project files.

Glazed versus colour-body porcelain

Choose colour-body porcelain where chips must be less visible and long-term wear is a concern. Choose glazed porcelain when you want a specific surface finish, texture or printed look. Ask the supplier how each product will age under your expected use.

Step 3: choose finish, size and grout strategy

Finish, tile size and grout joint planning shape the final appearance and can affect installation complexity and long-term maintenance.

Tile size and visual scale

Large-format tiles reduce visible grout lines and can visually expand a room, but they require a flatter substrate and more careful handling. If you plan large-format porcelain, confirm substrate levelling requirements and consider a dry layout or mock-up before ordering full boxes.

Grout, rectified edges and joint planning

Rectified tiles have mechanically precise edges and allow narrow grout joints for a cleaner look. Wider joints can accommodate movement and imperfect substrates. Grout colour also affects perceived tile colour and maintenance. Discuss joint width, grout type and movement joints with the tile supplier and installer.

Step 4: test samples at home and what to inspect

Do not buy a full order from showroom lighting alone. Metro Tiles & Flooring offers take-home samples you can test in your actual lighting and against your finishes. Use this inspection protocol.

1. View samples at three times of day under natural and artificial light to check shade and undertones.
2. Compare multiple pieces from different boxes to inspect shade and vein variation.
3. For wet areas, wet the sample to judge slip feel and texture.
4. Lay samples against cabinetry, counters and trim to detect colour clashes.
5. Photograph samples in place and note product code, finish and box numbers for ordering.

Also mock a grout joint and trim detail to visualise the finished surface. Metro Tiles & Flooring stocks curated lines including La Platera if you want a specific European look. la platera.

Step 5: assess the subfloor, installation and condo soundproof needs

Tile performance depends on a proper substrate and correct installation. Large-format and rectified tiles need very flat, level subfloors. If you plan underfloor heating, confirm the tile, adhesive and heating system are compatible. For condo projects, check bylaws for required soundproofing and choose a compliant underlayment. Metro Tiles & Flooring provides guidance on condo soundproof underlayment and offers professional installation and GTA delivery. Metro Tiles & Flooring, Solidshape.

When to hire a professional

• Large-format tile or layouts that need precision and levelling
• Uneven, damaged or moisture-compromised subfloors
• Exterior installations where freeze-thaw performance matters
• Projects subject to condo soundproofing bylaws
• Underfloor heating integration or specialized adhesives

If any of these apply, get a professional inspection and a written installation plan before ordering tiles.

Step 6: confirm warranties, maintenance and long-term care

Request both manufacturer and installer warranties in writing. Confirm recommended grout, sealant and cleaning products, and understand maintenance frequency for your chosen finish. For exterior use, always verify freeze-thaw suitability in the manufacturer documentation. Keep spare tiles from the same production batch for future repairs. Manufacturer technical sheets are the authoritative source for care recommendations. Daltile, Flooring Canada.

Frequently asked questions

What is the difference between porcelain and ceramic tile and when should I choose porcelain

Porcelain is fired at higher temperatures from denser clays, making it harder and less porous than most ceramic tiles. Choose porcelain when you need greater moisture resistance, stain resistance and durability for floors, exterior areas or high-traffic locations. See Flooring Canada for a concise technical explanation. What Is Porcelain Tile.

How do I know if a porcelain tile is safe for a bathroom or shower floor

Check the published slip resistance rating and test a sample wet and dry. For shower floors, choose a textured or rated tile and confirm the manufacturer or supplier testing. If building code or condo rules apply, request the official test data for your records. Solidshape.

Can I use porcelain tile outdoors in the GTA and what should I check for freeze-thaw resistance

Some porcelain tiles are rated for exterior use and freeze-thaw conditions, but not all are. Confirm the manufacturer’s exterior or freeze-thaw statement and the water absorption rating before installing outdoors. Daltile.

Do rectified-edge tiles mean I can use no grout and what grout width should I plan for

Rectified edges allow very narrow joints, but you still need grout to accommodate movement and keep dirt out. Joint width depends on tile format, subfloor flatness and movement requirements; discuss exact joint widths with your installer and supplier.

Is porcelain tile compatible with underfloor heating and condo soundproof underlayment requirements

Porcelain is compatible with underfloor heating when the tile, adhesive and heating system are specified to work together. For condos, check bylaws for soundproofing standards and choose a compliant underlayment. Metro Tiles & Flooring can advise on compatible products and installation approaches.
