Tile Size on a Sloped Floor
Large tile cannot bend, and a shower floor has to. The size limits applied at walk in shower installation lakewood ca nexusphiladelphia come from the fall rather than from taste, since a Lakewood shower floor dropping a quarter inch per foot needs a piece small enough to follow the plane it is bedded on.
Four Planes Means Small Pieces
A centre drain creates four sloping triangles meeting at diagonal ridges. Nothing rigid can span those ridges, so the floor takes mosaic, typically two inch or smaller, mounted on sheets that flex at every joint. Hexagonal and penny formats do this particularly well because they have no long straight edge to fight the change of angle.
One Plane Opens It Up
With a linear drain the floor is a single flat plane, and a single plane can take any tile at all. That is the practical reason a linear unit gets specified far more than the appearance of the grate: it lets the shower floor carry the same large format porcelain as the room outside it, which makes the space read as one.
Grout Joint Count Is the Trade Off
Mosaic gives grip from the sheer number of joints, and gives cleaning from the same number. Large format gives an easy wipe and less grip when wet. Neither is wrong, and the honest way to choose is by who uses the shower and how often anybody is going to be on their knees with a brush.
Cuts at the Drain
Around a round drain, the cut is a curve in every surrounding piece, which is slow work and looks best in mosaic. Around a linear unit the cut is straight and lands under the flange. Set out from the drain outward so the cuts fall at the walls where a bench or a curb will cover them.
Check the Bed Before Setting
Straightedge the finished bed in both directions and along the ridges. Every high spot becomes lippage that a bare foot finds immediately. On a mortar bed this is the last chance to correct anything, since once the tile is in thinset the plane is fixed for the life of the shower.
