Installation costs for a tiled walk in shower starts at $25.00 per square foot which includes the needed cement backer board and tiles as well as labor cost.
You can expect to pay around $2,000.00 to $2,500.00 for a professionally installed tiled walk in shower.
My tiled walk in shower costed me $2,300.00 with materials and labor charges for a professionally installed tiled shower.
A handyman could likely do it cheaper but to get a good job you need a professional who works with tiled showers all the time.
