Guest Bathroom

Goal

Everything is dated. Need a fresh look. (See pics below)
Simplify. Wall paint used 3 different colors, and has horizontal bar across the wall. Need to remove bar and use just one wall paint color (eg, white)
Shower area is very small. Need to enlarge space (no need to do this now)

Style

Prefer bright colors to brighten space.
Prefer matte over shiny surface for tiles.
No more than 2 shapes in tile choices to avoid busy patterns.

Vanity (already bought)

Atencio 36'' Single Bathroom Vanity; most likely will swap handles to matte black

Vanity faucet (already bought)

Moen Gibson Two-Handle Widespread Bathroom Faucet black; shower head will be paired with the same color

Room floor tile (already bought)

I bought 2 different types of tiles.

Betera 13" x 13" Ceramic Patterned Floor Tile for a classic / retro look for a stronger visual impact (in picture below)
Dalton 12" x 24" Porcelain Mosaic Tile for clean look (preferred) - see product in link

Vanity mirror (already bought)

Shower space

Expand shower space to 48” wide, push the wall toward office closet. Keep a shallow office closet behind shower space. (Examples below)

Clean up the office closet area - remove shelves, door frame, level door frame to closet ceiling height

Shower glass door or panel

fixed frameless glass panel. The glass door I bought (below middle) might not fit. Could replace with something like this (below right)

Shower wall tile

Prefer mosaic to make the wall look like one piece. Do not prefer large tiles and obvious grout lines to cut the already small wall space into pieces.

classic black and white porcelain mosaic for a strong visual impact, classic look

Shower floor tile

same as the room floor tile above (Dalton 12" x 24" Porcelain Mosaic Tile)

Shower head (already bought)
