When stacking walls, bathtubs, or shower areas, start by finding the center point of the wall. Use the level to draw a plumb line in the middle of the wall. Align the loose tile lines at the bottom of the wall from the centerline, leaving a uniform connection between the tiles. If your tiles have inseparable separators, they can be separated to automatically leave 1/16 consistent connection parts. If this layout leaves small pieces (less than 1/2 tile) on the wall then adjust the centerline of the plumb half the tile closer to the sidewall. Meanwhile, if you want to buy the best tiles, we suggest you check out tile shops in portsmouth.
Now determine the lowest point of the floor (or tub) horizontally using levels. Here, you must stack two tiles and draw a horizontal line at the top of it on the wall. With a level, continue the lines around all the sidewalls into tiles. This line is a guideline for the first row of tiles specified above.
Begin to install the tile to the center of the wall above the horizontal guide. Install half the back wall at once. Set the last two bottom rows. Cut and fit the bottom tile against the floor (or tub) if not level. Leave a gap of 1/8 above the tub to caulking to seal the tub.
Repeat the previous process for the sidewall. Mark outside the tile lines on the wall that will not fully tile to spread the adhesive.
Leave the tile where you plan to install ceramic accessories (soap dish, towel bars, etc.) Use bullnose pieces to finish the edges on the wall if necessary.
When installing the counter, arrange the tiles from front to back. Start with counter trim then set the tiles in the first row working backward, so all the pieces are made in the back row against the wall.
Snap parallel chalk lines on the substrate as needed to keep the lines straight.
For the backsplash, match the joint with the countertop tile. Start with a full tile at the counter, working so that all the pieces are made in the top row under the cabinet. Use cut corners of patch corners on walls or flat sides. The ceramic countertop must have a backsplash tile at least four inches high for protection.
