At that age, I would say that it would be best not to touch anything. You can give an allowance for something or just lower the price some. Curb appeal gets the person in the house, kitchen and bathrooms sell the house. What you will spend on the bathroom will be more than you will get back unless you do the work yourself.It is a 10 year old townhome. Kitchen has granite counters. Kitchen appliances are from date of construction. Custom built kitchen cabinets. 'Wood' tile floors everywhere except bedrooms that have carpet. Have thought about switching out the tile floors since they are dark brown to a lighter brighter color.
We compare houses more than anything, (appliances are worth 0, they are considered personal property). I've seen pretty nice showers in some medium level houses, if you plan to live there and enjoy it, great, but it might give you a grand bump in the long run. If you house is a young couples house, then at least one tub somewhere for kids' bath is important. If for older people, they will want zero entry showers to get in and out of. The extra space may be best used as an additional walk in closet space. Cheap cost and something a woman might really enjoy in a house.
