Shower vs tub (already a tub in 2nd bathroom)

[Shannon Leight]

Hello all,

This is my first flip. I will have a tub in the second bathroom. This is not a luxury property. For the master bath, I am trying to figure out if I should go with a walk-in shower or a tub. I have read that showers are more expensive. However, I see nice shower doors like this for around $500:

For the shower floor, I actually prefer the uncluttered look of shower pans which are not much money (and will match the pure white vanity countertops). Therefore, it seems it would not cost more for a shower. Am I missing something? A bit more wall tile, yes, but no tub. 

Also, I am thinking of larger format tiles (9x18) for shower walls (marble-looking ceramic) which will should save money too such as this. Am foreseeable problems with this?

Am I wrong? I do not want to do this if it will end up costing significantly more than a tub.

REALLY appreciate your help!!

Have a great day:-)
