a first spacer and a second spacer disposed between the first fastener and the handle;

wherein each of the first fastener and second fastener comprises a shank and a projection, the projection extending radially from the shank, wherein the projection of each of the first fastener and the second fastener is structured to be received within the respective first boss and the second boss; and

wherein at least one of the first spacer is structured to be received within the first boss, or the second spacer is structured to receive a portion of the first boss.

2. The handle assembly of claim 1 , wherein each of the first fastener and the second fastener further comprises a head coupled to the shank;

wherein the head is disposed a first end and the shank extends from the head to a second end opposite the first end.

3. The handle assembly of claim 2 , wherein one of the first fastener and the second fastener comprises a tapered surface disposed between the shank and the head.

4. The handle assembly of claim 2 , wherein a diameter of the shank is less than a diameter of the head.

5. The handle assembly of claim 1 , wherein the first boss comprises a first receiver and the second boss comprises a second receiver, and wherein the first fastener is received within the first receiver of the first boss and the second fastener is received within the second receiver of the second boss.

6. The handle assembly of claim 5 , wherein the first receiver is concentric with a central axis of the first boss and the second receiver is concentric with a central axis of the second boss.

7. The handle assembly of claim 6 , wherein the first receiver and the second receiver are coupled to the respective first boss and the second boss.

9. The handle assembly of claim 1 , wherein each of the first boss and the second boss extend orthogonally from the handle.

10. A door assembly for a shower, the door assembly comprising:

a substrate comprising at least one aperture;

a handle assembly structured to couple to the substrate, the handle assembly comprising:

a handle comprising a first boss and a second boss, the second boss spaced from the first boss, the first boss and second boss coupled to and extending from a same side of the handle;

a first fastener and a second fastener, the first fastener and the second fastener structured to couple to the handle via the first boss and the second boss, respectively; and

a first spacer and a second spacer disposed between the first fastener and the handle, wherein at least one of the first spacer is structured to be received within the first boss, or the second spacer is structured to receive a portion of the first boss; and

wherein each of the first fastener and second fastener comprises a shank and a projection, the projection extending radially from the shank, wherein the projection of each of the first fastener and the second fastener is structured to be received within the respective first boss and the second boss.

11. The door assembly of claim 10 , wherein the at least one aperture comprises a first aperture and a second aperture, wherein the first fastener is structured to extend at least partially through the first aperture and the second fastener is structured to extend at least partially through the second aperture.

12. The door assembly of claim 11 , wherein the first boss comprises a first receiver and the second boss comprises a second receiver, and wherein the first fastener is received within the first receiver of the first boss and the second fastener is received within the second receiver of the second boss.

14. The door assembly of claim 11 , wherein the first spacer comprises a first portion and a second portion, wherein the first portion is disposed between the first fastener and the substrate and the second portion is structured to extend through the first aperture and into the first boss.

15. The door assembly of claim 11 , wherein the first boss defines a sole, the sole being disposed substantially parallel to the substrate.

16. The door assembly of claim 15 , wherein the second spacer is disposed between the sole and the substrate, the second spacer structured to prevent the first fastener from interfacing with the substrate.

17. The door assembly of claim 10 , wherein each of the first fastener and the second fastener further comprises a head coupled to the shank;

wherein the head is disposed a first end and the shank extends from the head to a second end opposite the first end, the projection disposed proximate to the second end.
