This document summarizes different types of bathtubs and traps used in building services. It describes recessed, corner, freestanding, clawfoot, pedestal, platform, and whirlpool bathtubs. It also discusses materials used for bathtubs like acrylic, cast polymer, cultured marble, enameled cast iron, enameled steel, fiberglass, and solid surface. For traps, it covers floor/nahani traps, multifloor traps, and adjustable floor traps. The key functions of traps to prevent passage of foul gases and air through drainage systems depending on water seal level are also highlighted.

Bathtub• An alcove or "recessed" tub is
typically rectangular in shape and is
installed adjacent to three walls, leaving
one side of the tub accessible.
• The front and back of the tub and one
side are bordered by bathroom walls or

7. Freestanding Bathtubs
• A free-standing tub simply sits by itself on the
bathroom floor with no adjacent support structure
i.e. walls.
• These kinds of installations obviously need to be
located near the delivery and drain plumbing.
• Easy to install and doesn’t require any special
faucet drilling. May be able to integrate a
shower.
• These bathtubs are usually made out of cast iron,
porcelain, and acrylic.
• Clawfoot baths and pedestal baths are technically
'freestanding baths', but the category itself also
includes many other varieties such as vintage tubs
,slipper and deep soaker tubs.

8. Clawfoot & Pedestal
Bathtub
• Clawfoot baths are baths that sit
on four clawed feet. Clawfoot
bathtubs are the oldest and
simplest form of bathtubs being
used since decades.
• Slipper tubs feature a high, sloped
end to allow for greater comfort,
and double ended tubs which are
sloped at both ends.
• Pedestal tub sits on a pedestal
rather than on clawed feet.
• They are usually manufactured
out of porcelain, acrylic, cast iron,
or steel.

10. Platform/Drop-In
Bathtubs• A drop-in bath is one that's designed to
either drop into a cavity in the floor or a
raised platform for a (more or less) flush
finish and impart the feel of a swimming
pool.
• Easy to clean and offers versatile
placement possibilities.
• Integrated faucets are installed.
• The only downside of these bathtubs is
that it is slightly hazardous to come out
of the bathtub as one needs to take long
steps.
• Another type of drop-in bath is the
overflow tub.

be the peak of progressing technology,
sophistication and luxury.

installed, which rotates the water in the
bath for relaxation and massage.
• They offer health benefits like improved
circulation.

in commercial residential areas, spas
and buildings.

13. Walk-in / Gated baths
• Walk-in and gated baths feature high
walls and a seat in the tub, with a
door that opens up from one side to
allow the bather to walk directly in
without having to step over the wall
of the tub.
• These tubs are typically used to help
the disabled and elderly to bathe
freely with minimal assistance.
• The design typically allows the
bather to enter, sit upright without
having to lower themselves in, close
the door and fill the tub to the desired
height.
• The door has a seal on it that
allows the tub to contain the
water when it's filled..

14. Bathtub Materials
Acrylic:
• Acrylic sheets are heated,
formed into a mold and
reinforced with fiberglass, after
which wood or metal
reinforcement is usually added.
• Offer a wide choice of styles
and shapes.Resistant to
abrasion and fading
• Lightweight
• Hold heat well if insulated
• More expensive
• May scratch
Cast Polymer:
•Solid-color polymer-based
materials often made to resemble
onyx or granite. Finished with a
polyester gel coat.
•Mimic the look of stone while
offering the flexibility of synthetic
material.
•Thick
•Retain heat well
•Gel coating is somewhat less
durable than acrylic

• More expensive
Enameled Cast Iron
• Cast iron molded into a
bathtub shape and finished
with enamel. Generally
thicker than other materials.
• Durable and solid
• Available in a range of
colors
• Retain heat well
• Excellent soundproofing
• Heavy may require−
structural reinforcement

16. Bathtub Materials

• Resembles cast iron and is
produced by spraying
enamel onto molded steel
and firing the tub at a high
temperature.
• Less expensive than cast
iron
• May chip somewhat easily
• Provide a smaller choice of
colors
• May be noisy when water
is
running
Fiberglass
• A fiberglass backing material finished with a
layer of polyester gel coat. Wood or metal
reinforcement is often added.
• Economical
• Offer a wide choice of styles and shapes
• Lightweight
• Don't retain heat as well
• Solid Surface
• Made with acrylic and/or polyester resins and
baked into sheets. Resin provides flexibility
while polyester provides dramatic coloring.
• Color and texture remain intact despite wear
• Retain heat well
• Available in a wide range of colors
• Stain-resistant

17. Traps
• A trap is a depressed or bent sanitary fitting which always remains
full of water. It‘s function in a drainage system is to prevent the
passage of foul gases or air through it. The effectiveness of the trap
usually depends on the water seal.
