Ceiling to floor doors.

No one needs to see your feet. The door is closed. You got no business here. Walk on. Find another cubicle.

Soundproofing on all public toilets. Prolong the romance in relationships.

No touch flush. You wave a hand in front of a sensor to flush on all toilets. The next time you take your partner’s hand, you’ll know that slender feminine hand no longer has to turn a cistern.

25 years from now, the world will be full of young women who’ve never had to flush in the traditional sense. The world will be a better place. The human wrist will evolve and will arrive at a point where it won’t know how to flush.

No more communal toilets. Landlords, let your tenants live as you would wish your children to live. Stop thinking with your pockets.
