Bathroom Design and visualisation

Hi all,
Just to confirm... People without bathroom projects pictures will be declined, so I can narrow down my choice...
I need bathroom design and 3D visualisation.
The bathroom will be completely demolished including the wall that separate the wetroom with the utility room and all the walls will be drywalls.
The design will be for 65+ age people, so all safety antislippery aspects needs to be considered.
Overall sizes shown are accurate as it is at the moment, however after installing drywalls size will change slightly.
Country where the bathroom will be made is Bulgaria, however even that wetroom are standard there, that won't be the case in this design.
Only wet area to be considered - the shower cabin.
The Design Must have:
- Boiler installed horizontally as close to the ceiling as possible, covered by tiling ceiling at 45degrees.
- Drywall ceiling with extraction above the shower room
- electric heating to be considered
- Washing machine and tumble dryer
- Shower cabin
- Sink and Mirror for all bathroom needs
- Tiles to the floor, but some walls will be painted(or big mirror) to achieve lower overall price.
Possible extras:
- Additional toilet as shown (currently the toilet shown in the sketch is separate and too small)
- drywall shelves to hide pipes
- possible tumbledryer installed above the washing machine

What I expect to see is:
Design that doesn't show too futuristic bathroom designs, but more practical and realistic making it easy to implement.
Colours to be chosen wisely so we can choose tiles that are very close to your design ( No guidance from me here)
The design has to consider practicality, residents age, average budget

STEP FILES WILL BE ATTACHED
Sizes for Toilet, sink, boiler, shower cabin, washing machine and tumble dryer are estimated on the model.
The wall circled with blue pen will be demolished.
Any questions will be quickly answered and any additional information provided.

Thank you very much for your time!
