A step-by-step guide to installing Stargazy Speedwell tile as a bathroom splashback, including measuring, ordering samples, cutting, and sealing for a lasting finish.

Quick answer

Use Stargazy Speedwell tile on a bathroom splashback by first ordering a sample to check the hand-screened finish, then plan a layout that centers the star pattern, cut around fixtures, and seal the tiled edge with a waterproof silicone.

Why Speedwell suits a bathroom splashback

The 13 x 13cm size gives you flexibility for small bathroom tile splashback areas, and the star motif adds a decorative focal point without overwhelming a compact wall. Because the tiles are hand screened, expect slight variations in texture and finish; that is part of the character, not a defect.

For a blue patterned tile bathroom, Speedwell works well as a full splashback behind a basin or along a bath edge, but it can also be used as a border or panel. The choice of base tile affects the final look, so decide whether you want the pattern to sit on a lighter or darker ground before you commit.

What to check before you start

Measure the exact splashback area and subtract for any mirrors, sockets, or fixtures. Order at least 10% extra tiles to allow for cuts and pattern matching, and always order a sample first to confirm you are happy with the hand-screened pattern in your own light.

Check that your wall is flat, dry, and sound. Bathroom walls can be uneven, so use a straightedge to identify high and low spots; you may need to skim the wall or use a thicker adhesive bed. Also confirm the substrate is suitable for tiling and that any existing paint or wallpaper is removed.

Step-by-step installation

Order a sample and check the finish: Order a sample of Stargazy Speedwell on your preferred base tile and view it in your bathroom lighting. Because tiles are hand screened, texture and finish may vary; make sure you are happy with the pattern before ordering the full quantity. Do not skip the sample; hand-screened variation is normal but should be seen in person.
Measure and plan the layout: Measure the splashback area and mark the centre point. Dry-lay the tiles to find the best starting point, keeping the star pattern balanced and avoiding narrow cuts at edges. For a small bathroom tile splashback, consider starting from the centre of the most visible wall. A dry layout prevents awkward slivers and keeps the pattern symmetrical.
Prepare the wall and gather tools: Clean the wall, remove any loose material, and prime if required. Have ready a notched trowel, tile adhesive suitable for bathrooms, a tile cutter, spacers, a level, and a waterproof silicone for the edges. Check the adhesive is suitable for the substrate and bathroom humidity.
Apply adhesive and set the tiles: Spread adhesive in small sections using the notched trowel, then press tiles into place with a slight twisting motion. Use spacers to maintain even joints, and check regularly with a level. Work in manageable areas so the adhesive does not skin over. Do not spread more adhesive than you can tile within its open time.
Cut around fixtures and edges: For sockets and pipework, measure carefully and use a tile cutter or hole saw. For edges, a wet saw gives clean cuts. Always cut test pieces first if you are unsure, and keep the factory edge on visible outer corners where possible. Measure twice and cut once; hand-screened tiles are less forgiving of mistakes.
Grout and seal: Once the adhesive is fully cured, grout with a waterproof grout, pressing it into the joints and wiping off excess before it dries. Finish by applying a bead of waterproof silicone along the bottom edge where the tiles meet the basin or bath, and around any penetrations. Silicone, not grout, is the flexible seal at movement joints.
